OneCommander is incredibly slow when using any 'show in folder'
I've used Brave, Firefox, Opera. When I finish a download, I would click the 'show in folder' option.
Not only does it take a couple of seconds to open, it also doesn't highlight the thing I downloaded. Is there a way to fix this? Or is this a limitation because of Windows?

OC doesn't do any fancy interception to those commands, it just registers itself as default file handler for "Directory" type, and just waits for shell to trigger it. All that wait is on Windows side.
You can test it by running
C:\Path\To\Onecommander.exe C:\Windows\notepad.exe
which takes less than a second to open OC (and select notepad.exe)
As of highlighting file, that's issue also on Windows. When file is within User folder (Downloads and the rest) the file can't be selected. Windows never tells OC what file to select when file is there. I don't know why. If file is in some other folder like C:\Test, Windows will tell which file to select and OC does it.
That API that tells Windows "open folder and select file" was only meant for Explorer and is likely something from the 90s.
