Helix-like info boxes for sequences of keys (minor modes)

In Helix, sequence keybinds (such as g and d in Sioyek) will open an info box on the bottom right of the window displaying all available keybinds that can complete the sequence. I think this sort of feature would make Sioyek much more user friendly when using keybinds.

The status bar also displays any keys that have been pressed so far, making the current state of the program much more explicit.

Helix has many UX improvements over vim that may be worth exploring for Sioyek.
