There is a 'key ring' in both Classic AND Enhanced Edition of D:OS1. I suppose Larian made a change in EE that keys would also be visible in the regular inventory because a lot of people did not find the 'Keys' tab on the left side of the inventory in Classic.
So one difference between Classic and EE was that objects flagged as keys would no longer be hidden from normal inventory view. An option to show/hide would have been helpful but well, needs time to implement ...
As long as chests and doors can be smashed there will always be leftover keys at the end of a game ...
The functionality to open doors and chests with any character was in EE too (Magic Pockets), but the info popup was annoying enough (but that's a matter of taste) to make me remove it completely for shovels and pickaxes in a mod ;-)
