One thing that I wish Bethesda RPGs had for a long time, is a way in-game to tell when is safe to use a container or interior to add my items.
You open the container and the icon will appear at the corner of the HUD, indicating that is set to respawn.
With interiors, the map will tell when is safe to use it as a "home". So your items will not disappear because an NPC, get replaced when the interior reset, or something spawn right int it, triggering the havok to throw your item somewhere.
Another must, is be able to set the console key in the in-game key bindings. Had an issue with Skyrim, because the quote key was the same as the open/close console. Making difficult to use some commands.
