I would like an option to always dump a .flg upon game end, without any sort of prompt. I'd like it so I can record stats from every game and do neat(er) stats things with the data. I'm sure some (granted, not many) people out there would also like a record of every game to go back to.
(For P16 and below, I'm using Sage to auto-answer the flg prompt, but P17 changed the end-of-game prompts such that that method is no longer possible, or at least I don't know how to do it atm. And an option built in to ADOM would let me enforce it for non-Sage users too.)
