This question is asked at the Interactive Fiction Database, but I wanted to repeat it here.

Clickable buttons on a frame for NPC interaction (regards NPC name as helper word).
The dropdown lists are inconveniently positioned.

Mouse rollover in popup for reading maps (collapsed in normal view).
Multiple tabs for game save slots with set or reset skill level if available.
