[Feature Request] Tab/Shift+Tab Navigation

[jitendradara12]

Tabs get registered as whitespaces in the launcher instead of moving down the list (common in similar UIs).

I tried to implement this myself and kinda made it work for myself (#93)
so I'm opening this feature request in hopes that someone can actually implement it.

Details:

• Pressing TAB should move down the list (not input a whitespace.)
• Shift+Tab should move up.
