So, here's my contribution to the project, for what it's worth - mock-up of a new layout for the Battle editor.
It's a minor pet peeve of mine that you have to constantly be scrolling up and down in the editor to view status and elemental properties. Extending the window size to no longer need that was my initial intent. With the window lengthened by less than 100 pixels, all three of these windows can be viewed in their entirety, no scrolling needed. I also moved the No Harm/Can Dodge fields for Special Attack over a bit and shortened the animation dropdown display, allowing the Special Attack box to be thinner. I also moved Experience and Gil down to be beside the Morph box so they don't take up a full row below primary stats but are still ground in the "battle spoils" info, and moved down the Level-HP-MP boxes so they seem more distinct from the Name/Number part in the upper-left.
Finally, in my initial mock-up there was large white space in the lower left. Then I recalled past feature ideas for expanding item drops and steals to 4 items, or possibly expanding Rage and Sketch to 4 attacks, were ideas being tossed around. Well, if either of those becomes a thing, there's room to add new Rage, Sketch, and Item fields. And if not, we have that empty space to possibly add some other options.
