Hello, hello~. I've got an incredibly minor suggestion that I forgot about until like, 5 minutes ago.
When you enter an instance dungeon, a window pops up in the lower lefthand corner. You can exit it out by clicking on it or pressing Esc. And then you have to do it again and again since the window pops back up every time you go through a warp. It's not a big deal, just a small inconvenience.
It would be nice if it was there when you first enter the dungeon, showing how much time you've got left. But it's kind of in-your-face if it's constantly appearing on your screen.
