I think that along with the dialouge editor there should be a way to get rid of the invisible wall that pops up with every message. I belive that the invis. wall is a part of classic zelda, but there are certain times that it just gets in the way.
Dialouge/Invis Wall
The purpose of the wall in the original was to stop Link from walking under the text, with the dungeons sculpted to such a thing being irrelevant (or even part of the puzzle, in the case of the Goriya). An option for modern-style text that goes away (and thus, removing the wall either way) I would think would be a staple for a dialogue editor.
Oh yes I want this! Now we can have NPCs on the upper half of the screen!
