Suggestions for V4

[Dumitru Damaschin]

1."F2" should also support editing aliases (group names, tab names, etc.).

2.The contour/shadow effects across the page are visually noisy. in my opinion should be removed.

3.Right-clicking the column headers should allow editing/adding/removing columns through a dedicated customization window.

I’d also like the ability to display all available file version-related metadata (Version, File Version, Product Version, etc.). In general, columns should be much more customizable.

At the moment, some folders still show different columns and it’s not always clear why.

4.Some images/icons look slightly blurry or out of focus.

The same applies to parts of the text rendering.

5.This three-dot menu could probably be removed in favor of drag & drop interactions and right-click context menus.

6.Some buttons are redundant, and others should at least be optional/toggleable to reduce UI clutter.

Also these should probably be optional.

7.This area would benefit from a bit more bottom padding/margin.

8.These separator/grid lines should come back as the default behavior.

9.Folder size calculation still has performance/stability issues.

I wouldn't mind an option that indexes/caches everything based on the "last modify date" (witch probably should also be custom managed, because windows doesen't always assign the most recent date of the folder - based on his content).

For performance, I strongly suggest taking inspiration from WizTree, witch is able to scan my entire "C:" in 3.28 seconds (1,300,000 files and 269,000 folders). So even if windows fails to track every file changed (unlikely?), MFT will be very fast to allineate the folder's data.

10.Ctrl+F and the in-page filter should behave as the same unified feature.

Instead of opening a separate page, filtering should happen directly in the current folder using a tree-like structure similar to the screenshot.

Double-clicking folders or navigating to parent directories should preserve the active filter.

I’d strongly recommend taking inspiration from Everything by Voidtools. The first indexing/cache creation may take some time, but after that searches are nearly instant and updates are extremely fast if managed correctly.

Ctrl+Alt+F could instead trigger a global filter across all panes.

11.Ctrl+Shift+F should search inside file contents recursively (including subfolders).

For this, I’d suggest taking inspiration from ldufr’s Search project, which is based on ripgrep:
https://github.com/ldufr/search

Ctrl+Shift+Alt+F could perform the same operation globally across all panes.

It should be possible either to:

• list only the first match per file, or
• display all occurrences(preferably, I bet you could find a nice solution).

Double-clicking a result row should open the file in the default application at the exact matching line.

For VS Code, for example:
Code.exe --goto {file}:{line}

More generally, it would be great to support customizable commands with placeholders.

12.In dual/triple pane mode, it would be amazing to support some WinMerge / Beyond Compare-style features:

• Align files/folders with the same name on the same row.
• Selecting a file/folder in one pane should automatically select its counterparts in the other panes.
• Double-clicking a folder should open the corresponding folder in all panes simultaneously.
• Double-clicking a file should open the configured comparison tool/editor (WinMerge, KDiff, VS Code diff, etc.).
  Example:
  code --diff {file1} {file2}
• File/folder comparison based on multiple criteria:
  • last modified date
  • size
  • version
  • full content (optionally skipping very large files)
  • etc.
• Better or customizable shortcuts for copy/move operations between panes, for example:
  • Ctrl + Right Arrow
  • Ctrl + Alt + Right Arrow

I think implementing the last four points before the V4 release would make the product extremely compelling as an all-in-one power-user tool.

13.Ability to pin tabs.

14.In the exact same way we save directories, would be nice to save currently open tabs/panes as a group/session.

15.Option to replace Windows Explorer with OneCommander in a more native/system-integrated way.

16.Some custom contextual menus aren't visibile on OC

Overall, after trying the new version, I’m satisfied. The direction is genuinely promising. Keep up the great work, and don’t hesitate to leverage tools like Claude Code or similar.

These kinds of apps are searched for their customization and customizability, so don’t be afraid to make strong authorial/design decisions.

Thanks.
