I'm not sure what others feel about items on the ground, but depending on where they are they might be nigh impossible to find without wasting precious TUs and awkwardly going into the inventory screen.
Proximity grenades are the bane of my existence when I forget about them, too. One might say that it's part of the game and if I forget about them it's tough sh** if I blow up my own troops, but I feel like the soldiers should be a bit more observant than I am.
It'd be nice if hovering the cursor over a square with items could some how indicate if something was there, or possibly give a text readout on the screen. I personally would like it if prox grenades could give off a dull flash that can compensate for isometric walls that completely hide them.
Thank you for reading my first post and I hope I posted in the right area.
