Is this what the komorebic identify-border-overflow-application command is for? Genuinely asking, because I'm not sure.

This command is primarily to identify Electron applications that deliberately overflow the system-wide fixed invisible borders around every window.

There currently is no command exposed to modify the width of the active window border, though from the screenshot I believe this may be something specific to Windows 10 (which I'm not running anymore) if the generated configuration file with application-specific fixes has been applied.

For anyone who wants to work on this, I'd suggest two ways forward: Exposing a command to manually configure active border widths, or adding a Windows 10-specific logic fork to the current border width calculation values.

Setting custom border widths and offsets is now supported with komorebic commands: active-window-border-width and active-window-border-offset.
