What enhancement I need or want in Haiku?

I use 3 level keymap (3th level with alt-option key), and I run in some problem with hotkeys with alt (option), can I change that to control?

For example I have ‘+’ on 3 level, and I cannot use command+option+’+’ in Tracker window, because when I press command and option keys system seems expects hotkey from first keymap level not some command+‘some 3th level symbol’.

Can be this option of asigning hotkey key between control and alt(option) added to Haiku?

3 levels keymaps are common for non english users.
