1. I've looked into the font before, but it's a limitation with the font itself and is impossible to fix with just spacing changes. Unfortunately, that is largely here to stay. I'm going to go through it again soon and see if it can be improved. It's also a limitation with how the menu squeezes the text together. It *may* be possible to make each letter slightly wider by changing hard code data.
2. Having "Weapon / Armour" looks worse than Wpn Arm. They then don't align nicely and you have to also use Accessory, which looks even more stupid in the Equip menu
3. LV again aligns properly to HP MP and looks neat. Lv doesn't and also means I have to change an actual font texture which is not easy. The small v does not exist on that font.
4. All of the other changes ed up making other parts look weird. I'm afraid there really is no way to make it look any better, because changing one part ends up just making another part look crap. It's a shit engine and menu system. If you want to see what I mean, use photoshop and change things up. You'll find the difference ends up negligible.
5. I will look into moving the materia down, but if you look at it at the moment, the matreia name X is aligned with the "Ability List" word. The element word ends up aligned with the abilities. The matreia is aligned with the right side materia.
6. The avatar IS centred. It's just that you are not seeing the dark line on the border because of the dark red background. A lighter colour makes it look centred. One pixel change in hardcode results in 4 pixel change at that resolution... so that's as centred as the avatar can possibly get.
It's also an incredible amount of work to move things about. Every single item requires 2 edits X Y. But if you want to give me a picture of what you think is better, use PS.
Wouldn't "Equip xxx magic" (imperative mood) fit more ?
That's one for Covarr. I personally think it makes more sense to say what the materia does and other areas of the game are consistent with that, like the command menu.
Full Cure : Equips Full Cure magic, Shield : Equips Shield magic, and so on.. What's the point in being told that ?
A limitation with kernel size (I think the size is increased now) and also what the Japanese says. It doesn't offer any additional info. It just says "Equips Full Cure materia [possibly magic]". Other materias have an explanation. I could add an explanation but then I'm also changing the game and I don't like going too far, plus what explanation can you really give for "Full Cure"? "Fully restores HP to one target"? Materia help is largely redundant.
