I think a quick-win dev ticket that would add a lot more comfort to the playability of the game (and should be pretty easy to implement) would be to just expand the available keyboard keybind settings to a more robust level:

Alternate Hotkeys:
As simple as it sounds, just add an alternate hotkey column; e.g. I'd like to be able to move forward using 'W' as well as LMB+RMB.

Make all hotkeys configurable:
Add hotkeys like whole stack transfer and stack split to the settings UI so that they can also be remapped; e.g. I would like to swap what SHIFT and CTRL do.

I really enjoy your game! Thanks for the great work.
