did it work? just wanted to check :^)

[maddie480]

using the keyboard, some things are quite odd:

• on the Everest versions list, scrolling through the versions doesn't just move the cursor, it changes the selection, so choosing a version then moving down to select Install involves going left or right and hope to land on the bottom, and since there's no distinction between "focused" and "selected", it is unclear where the focus is
• on the Everest versions list, the scrollbar is extremely awkward, going down past the "Install" button makes it scroll down, and scrolling up doesn't work consistently
• on the main menu, going down skips from "manage installed mods" to "options & updates"
• I couldn't figure out how to use dropdowns with the keyboard
• on the main menu, about scrolling again: it's possible to get lost offscreen in Olympus News on the right

and on Steam Deck:

• using the d-pad in desktop mode (which I think is just mapping to the arrow keys) makes a button flash for a split second, as if keyboard nav was fighting against the mouse pointer
• using the "controller with camera controls" (which is pretty much "use the controller as a controller already!") behaves as if I'm holding a direction at all times
