You mention that the mouse can’t be used to do anything other than mouse over to look at things… I think you also mention that in the university series as well.
FYI the mouse does have features that can be used besides the nifty inspection. Pretty sure most if not all of these were present when I started playing in about August of 2016. You can left click somewhere and it gives you a marker and dots (like when looking around). If you click on that marker (or just double click) your character will move to where you clicked. If it’s a doorway you clicked on (to move) your character will open it just like on keyboard. Additionally right click is semi context based. For doors and such right click closes them, it’s also for examining stuff like vehicles or items on the ground.
Some difference between mouse movement and keyboard movement. Mouse movement will do some pathfinding for you (the dots are the path that will be taken). If you can’t inspect the tile (x?), ie you can’t see the tile, then you can’t click on it to move there. Finally all the movement seems to happen in one update, that is to say it doesn’t draw every step, just the final stop. I’d suggest, if safe mode is disabled, avoiding using mouse movement (or go in small steps) as with safe mode enabled the moment your character sees something dangerous they will stop before reaching the destination.
The mouse also has special features when engaged in ranged combat. Entering fire mode the box that appears on the right states Mouse: LMB: Target, Wheel: Cycle, RMB: Fire.
There may be other uses in there but that’s the stuff I’m aware of and use periodically (well I never used the right click before and I haven’t had a mouse with middle click in a long while). Also I don’t really play outside of windows tiles, I’d expect linux tiles mouse stuff to be present but mouse is probably reliant on SDL and hence the tiles version.
