So one of the features I saw listed that made me want Ace right away is being able to use more tilesets, because being limited to 5 pages is such a drag.
So from what I've seen, there are 4 different categories you can assign a map for tileset use: Field, Exterior, Interior, and Dungeon.
If I want access to all the in-game tilesets on one map, I assume I'd have to create a new category that has access to all default tilesets, right? I was sort of hoping that we would have more tabs than A-E, allowing us to import a ton of different tilesets and have access to ALL of them on a map. From what I understand though, we'd have to mix and match, almost making a custom tileset category for almost every map depending on what we want in that map.
