Sensuki Do you see the possibility to mod a UI like this into the game?
It's doable right and wouldn't take more than a few hours.
The problem with this particular UI is that it's
1) space inefficient (makes me think of really old Grimoire-like games where you've got a small rendering window and it's like looking through a peephole)
2) doesn't take into account the fact that casters can have much more spells and they wouldn't fit the predefined frame
3) the log would look ridiculous if resized vertically to accommodate a curious player
If somebody made a decent UI, I would've probably implemented it just for fun when I was still very active with the modding. Nobody did, though. There was a thread on obsidian forum where a few people made photoshop mockups of solid UI and then congratulated each other, patting each other on the back and whatnot, but all their UIs were just as bad and unusable as this one.
If somebody comes up with a cool UI, I might take some time off my own shit and just mod it in anyway. But I'm not counting on it.
