Thanks for the detailed breakdown, this is genuinely useful!
On the lag and click registration that's a known bug that's actually just been patched. Multiple clicks needed was a race condition between the UI updating and the click event firing. Should be fixed in the current build.
Crafting button flash on hover -noted, will look at that.
Wood Slope timing — you're right that dropping to 20 before it kicks in is too loose. The threshold should be higher so it catches the fire earlier. Adding that to the fix list.
Fuel warning - fair point. A low-fuel indicator near the generator or in the top bar is on the to-do list.
Warning indicators shifting layout - completely agree, that's bad UX. They should overlay or animate in without pushing buttons around.
Action slots + auto-repeat - the multi-slot penalty when auto fills all slots is a tension we're aware of. The idea behind it is "manual focus beats automation" but it lands as punishing rather than meaningful when you just want to set it and forget it. Worth rethinking.
Tech tab auto-unlock- the manual click is intentional as a moment of progression, but if it's purely linear with no real decision attached, your point stands. Might work better as a notification that pulls you there rather than a required click.
Appreciate you taking the time, especially twice. Keep the feedback coming!
