This one was a long time coming.
There was a bit of a bug with delays in the code, so that is now fixed.
Also, global hotkeys! They are now enabled. They are not changeable yet. Sorry about that. But you can enable/disable global hotkeys with F6 or from
Controls -> Enable Global Hotkeys. This will make space, k and delete globally act as they do when the app has focus.
Controls -> Disable Global Hotkeys will make them work only when the app has focus.
The split files still need to be set up by hand. Sample files are included.
