Introduce a new filename_format setting and UI to control yt-dlp output templates. ConfigManager now includes a default filename_format (%(title)s_%(resolution)s.%(ext)s). The DownloadSettingsDialog exposes a text input and help text for the format and saves the value to ConfigManager. DownloadThread now accepts a filename_format argument and uses it when building output templates for single videos and playlists. YTSageApp reads the config and passes the filename format into the download thread. Added corresponding English language strings.
Emit progress updates during URL analysis and simulate gradual progress for long-running yt-dlp operations. Added QTimer import and a progress_update Signal on AnalysisThread, with emits at multiple analysis milestones (e.g. 15, 30, 60, 70, 85, 90, 92, 95, 100). In AnalysisMixin introduced _analysis_timer and _fake_progress, connected thread progress to _handle_analysis_progress, and implemented a _update_fake_progress timer that slowly advances the progress bar between real updates. Timers are stopped on real progress, completion or error and the UI progress is reset appropriately to improve UX during long extraction steps.
Introduce check_ytdlp_deno_integration() in ytsage_yt_dlp.py to detect Deno integration by running `yt-dlp --verbose` and scanning debug output for JS runtimes containing "deno" (with timeout and logging/fallback).
Add SystemInfoThread (QThread) in ytsage_dialogs_base.py to collect yt-dlp, ffmpeg and deno presence, versions, paths, cache timestamps and integration status in the background, emitting the gathered info via info_ready. AboutDialog now starts the thread in update_system_info() and populates the UI asynchronously via _populate_system_info(), showing a small "+ yt-dlp" integration indicator next to the Deno status when detected. Refactors usage of version/cache lookups to use the thread-provided info dictionary.
Add streaming progress support to Deno upgrades and hook it into the GUI. upgrade_deno() now accepts an optional progress_callback and uses subprocess.Popen to read stdout line-by-line (line-buffered, utf-8, errors replaced), collecting output and invoking the callback as lines arrive. Added DenoUpdateThread (QThread) with finished/progress/error signals and replaced the previous background thread usage in the updater UI with this QThread. GUI slots strip ANSI escapes, truncate long messages, and update status text; buttons are re-enabled on finish/error. Improved logging and error handling for upgrade failures.
Introduce SmoothTabWidget and a FadingStackedWidget to provide cross-fade transitions between tabs. Added ytsage/gui/ytsage_smooth_tab_widget.py which implements a QTabBar + FadingStackedWidget (default 300ms fade) and overlay-based fade logic. Updated ytsage/gui/ytsage_gui_dialogs/ytsage_dialogs_custom.py to use SmoothTabWidget instead of QTabWidget and adjusted the stylesheet selector to target the new content frame (#tabContent) so existing styles continue to apply.
Add a safe blurred-overlay flow for modal dialogs by implementing run_dialog_with_blur and _apply_blur_to_pixmap on YTSageApp. The new flow captures a window screenshot, generates a blurred/dimmed pixmap via a QGraphicsScene + QGraphicsBlurEffect, shows it in an overlay QLabel with a fade-in, runs the dialog, and then removes the overlay.
Replace many direct dialog.exec() calls with run_dialog_with_blur(...) across the main GUI (download settings, about, history, playlist selection, custom options, cookie login, ffmpeg check, time range, setup success dialogs, etc.). Also add imports required for pixmap/graphics handling.
Make animate_widget_fade_in usage safer by checking for the method before calling it and falling back to setVisible(True) for format table and thumbnails to avoid QPainter/graphics-effect conflicts. Small comment/cleanup in fade-in/out methods.
Update ytsage/gui/ytsage_stylesheet.py to add explicit padding for various QPushButton:pressed rules (and QPushButton:checked:pressed) across multiple style blocks. These changes unify the visual spacing and touch feedback when buttons are pressed, ensuring consistent pressed-state layout and appearance.
Introduce a shake animation to visually indicate invalid inputs and wire it into validation/error flows. Changes: import QPoint; add animate_widget_shake(QWidget) implementation that uses QPropertyAnimation on widget.pos with keyframes; call the animation when URL/path/format validations fail and replace some direct status_label updates with set_status_message_animated. Updated files: ytsage/gui/ytsage_gui_main.py and ytsage/gui/ytsage_gui_analysis.py.
Hide the thumbnail QLabel before assigning the pixmap and trigger animate_widget_fade_in to smoothly fade the thumbnail into view. Keeps existing exception logging for thumbnail processing.
Use animated show/hide for playlist widgets and harden fade animations. Replace direct setVisible signal handlers with lambdas that call set_widget_visible_animated, and add set_widget_visible_animated to route to fade-in/out. Fade methods now stop opposing animations, reuse existing QGraphicsOpacityEffect when present, preserve current opacity as start values, and set effect opacity when creating a new effect. Also catch possible RuntimeError when stopping animations and keep animation references on widgets to avoid premature GC.
Make the format table invisible while it's populated and filtered to avoid visual artifacts, then animate its appearance with animate_widget_fade_in after initial filtering. This ensures a smoother UI when the table is first built.
Introduce smooth UI transitions by adding opacity-based animations. Import QGraphicsOpacityEffect and add animate_widget_fade_in, animate_widget_fade_out, and set_status_message_animated to cross-fade status text and fade buttons in/out. Update signal handlers and download flow to use the new animated status setter and fade methods instead of direct setText/setVisible calls. Keep animation references on widgets to avoid premature GC and remove effects after fade-out.
Moved all files from src/gui/ to ytsage/gui/ and updated import statements to use relative imports within the new package structure. This improves modularity and prepares the codebase for distribution as a proper Python package.
