One idea I've been thinking about was a hud installer that mods the base files directly, so that it for the most part works after updates and has the potential to be incredibly customizable. Give options like font usage, health/ammo positioning, backgrounds or shadows, etc. to the user rather than the hud maker, you know? In a way just make an easy to edit hud system rather than a single custom hud.
I'll help out with this for sure, but I'm wondering if a hodgepodge of people's favorites in one hud with little/no customization will really fix the issue of not enough good huds. There are just way too many personal preferences that go into it to have just one hud, unless we're talking about including a ridiculous amount of customization options.
