some suggestion

[Andrey]

Hello. I downloaded your program to try it out. It's a very unusual approach.

I'd like to make a couple of comments.
1. I'd like to see a proper window title. That is, the window name, then the menu, then the tabs. This makes it easier to drag it by the normal heading.
2. A toolbar should be added. At least with a minimal set: copy, paste, cut, undo, and large icons. The context menu is inconvenient for working with files. Buttons are much more convenient.

Come to discord to check v4 beta. Drag by window name needs a fix, but there is a toolbar you can customize

Thanks for noticing my comment.
I've looked at the screenshots so far. It looks good. I hope the button size will be adjustable. Small buttons are hard to hit and inconvenient to use. For example, I'm willing to sacrifice screen space for larger buttons.

Also, I think you should add checkboxes for file selection. That's great. No need to use the control key. Add buttons to invert the selection, etc.

Just don't copy the behavior from File Explorer.
So, we selected 10 files by clicking the checkbox.
Then we missed the checkbox on the 11th file, and the entire selection disappeared. Very bad.

This should be fixed. You can reset the selection either by switching to another folder or by clicking the checkbox in the title bar. I think that's much better.

Tanks!!!!!!

and add a button in the size column - calculate the size on demand. This is for folders.

Continuously scanning the disk is not correct, but on-demand is great.

Here's a good example from the OpenShell program.
Excellent toolbar. Very easy to use.

And there are even custom buttons.

The cut button is much larger than the standard one. It's very convenient to use.
That's the only reason I use it.
You can also create custom buttons with commands. For example, copy a path to the clipboard or copy and paste the file name. It's also very convenient.
