Leonid Nikitin	24446559b4	Merge pull request 'Версия 0.9.0' (#10 ) from develop into main Reviewed-on: #10	2025-05-25 23:13:25 +05:00
Leonid Nikitin	7340f43d6e	Remove unused helper function from ffplay.go The `PrepareBackgroundCommand` function has been removed because it prevents the program window from being displayed on Windows.	2025-05-25 22:51:59 +05:00
Leonid Nikitin	5ab11922b9	Select "Added Files" tab after dragging and dropping files. Ensure the "Added Files" tab is automatically selected after users drag and drop files for conversion. This improves user experience by guiding them to the newly added content.	2025-05-25 21:46:19 +05:00
Leonid Nikitin	5f72ce8c56	Update screenshot for GUI in FFmpeg documentation Replaced the GUI screenshot to reflect the latest interface changes. This ensures alignment with the current functionality and improves user clarity.	2025-05-25 01:48:33 +05:00
Leonid Nikitin	5b15848048	Update version to 0.9.0 Bump the application version from 0.8.0 to 0.9.0 in both `main.go` and `FyneApp.toml`. This reflects the latest changes and prepares the app for the next release.	2025-05-25 01:29:14 +05:00
Leonid Nikitin	84b36dd29e	Make it possible to drag and drop multiple files It is now possible to add multiple files before sending them to the processing queue.	2025-05-25 01:25:40 +05:00
Leonid Nikitin	82167f042f	Add theme management functionality to the application Implemented a theme management system allowing users to select and persist themes (default, light, dark) in the settings menu.	2025-05-23 20:18:05 +05:00
Leonid Nikitin	712ec2f182	Remove language selection to a new settings section.	2025-05-22 21:42:45 +05:00
Leonid Nikitin	883bf376b0	Add FFplay help feature and keyboard shortcut guide Introduced a new "Help FFplay" section in the help menu to provide information about FFplay player keyboard shortcuts and actions.	2025-05-21 00:22:42 +05:00
Leonid Nikitin	306383449a	Add FFplay support to the application Integrated FFplay functionality across the application. This includes support for setting up the FFplay path and invoking FFplay for media playback.	2025-05-19 22:49:09 +05:00
Leonid Nikitin	a831d56d93	Add localized error handling for database timeout Introduced a new localized error message "errorDatabaseTimeout" in multiple languages (English, Kazakh, Russian) and updated the `PanicError` method to handle database timeout errors more gracefully. This improves user feedback by providing context-specific error messages.	2025-05-18 19:32:57 +05:00
