I tried switching to US a few times, but every time muscle memory made me give up soonish - especially since there are big benefits to using same keyboard layout as other people in your office are using.

Also practically everytime I need to write a comment, commit message or email I need my č, š and ž. It's kinda nice to have them only a single keypress away.

My hack: use caps key to switch to local keyboard layout while holding it.

Love it! I use ctrl+space to switch, but your idea sounds even better
