Another thing that I recently discovered by accident. When you are in dungeons, if there's a spot that you want to go, bring up the map and click on that spot. It will now blink. Now no more trying to relocate that spot when you've gone down a few corriders, it'd be blinking until you click on it again.
Are you talking about the yellow map dungeon layout on the left side of the screen?
I didn't know that. Wow, after 13 years I still discover new hidden features.
On the topic of maps, you can write notes on your local town map. Click anywhere and start typing. Useful when you want to identify specific buildings. Or, when breaking through houses for thievery, it's useful to identify the houses you've already done or identify the houses that can't be entered.
