The tile mode with all its neat graphics has spoiled me. I tried playing ASCII mode a few days ago and suddenly everything seems harder to do. Can't recognize items from zapping wand of item detection (especially in vaults, in tile mode you can tell artifacts from their graphics 100% of the time), but that's a bit later in the game. Can't recognize friendlies/non-hostiles (the pickpocket alignment drop!) and unaware monsters without a 'l'ook command, that's really annoying. But the main issue I had were herbs. Tile mode includes an incredibly neat three step graphic showing the "health" of a herb patch so I know when I should stop picking up. In ASCII mode I destroyed absolutely every stable patch I found in UD, and that was with ~80 Herbalism. So, is there any way to recognize the patch state?
