V4 BETA

[OneCommander Support]

I’m looking for more people to try OneCommander v4 beta. Current public version is v3, but v4 has a lot of internal improvements: faster browsing, smoother scrolling, a new folder-size system, integrated Taskmaster file operations, better metadata/previews, improved email handling, customizable toolbar/icons/views, better session/window restore, and a major visual/theme overhaul.  

Biggest changes in v4 

1. Much faster and smoother file browsing

v4 has multiple performance rewrites: faster file rendering, smoother scrolling, better thumbnail handling, reduced UI stalls when browsing slow drives/network folders, and improved responsiveness while Windows or disks are slow to respond.

2. New folder-size system

Folder sizes no longer rely on Windows infotips. v4 has its own folder-size database, faster scanning, better handling of large folders, mount points, inaccessible folders, and eventually sorting by folder size once sizes are known.

3. Taskmaster is now integrated as the default file operation engine

Copy/move/delete/rename operations are now handled through the integrated Taskmaster system, with better tracking, UI feedback, copy-paste improvements, database updates for moved files, and undo support for file operations.

4. Major visual/theme overhaul

v4 introduces a much more customizable UI system: dark/light theme work, Mica/Acrylic effects, sharper icons, theme accent-color improvements, theme metadata, active/inactive browser styling, and a Theme Editor Helper window for testing theme controls.

5. Customizable toolbar, menus, icons, and views

V4 has a more classic toolbar, users can customize toolbar buttons, change toolbar/menu icons, use new Win11-style dual-tone icons, edit file views from the new Resources\Views structure, and adjust interface elements more deeply than in v3.

6. Better window/session management

v4 improves restoring windows and sessions, including multiple windows, virtual desktop restoration, saved windows, temporary windows, named windows, and new-window behavior. Autostart/session restore behavior was also improved.

7. Improved metadata, previews, and thumbnails

Metadata extraction was partially rewritten for speed and reliability. v4 adds or improves metadata for documents, PDFs, media duration/resolution/date taken, PSD files, email files, EXE certificates, cloud status, and richer details/preview panes.

8. Better email file support

Email handling has improved across Outlook, New Outlook, and Gmail drops. Email files now show metadata counts, body previews in rich view, additional details, naming-format presets, and improved formatting behavior.

9. Better search, sorting, and navigation

v4 includes settings search/filtering, grid view for search, better search-window layout, improved sorting controls, Alt+Left/Right navigation, more reliable focus behavior, and fixes for edge cases like searching names with periods.

10. Many stability fixes

The log includes repeated crash fixes, Recycle Bin fixes, startup fixes, updater fixes, Windows 10/11 visual fixes, network-path freeze prevention, folder watcher fixes, and many smaller regression fixes.

Important note for testers

v4 is still beta and focused mostly on stability, polish, themes, performance, and bug fixing. Some areas are still work-in-progress, especially theme keys, icons/logo, and visual consistency.
