This is a list of all UI mods for the EE games posted in this subforum, for your convenience. To be updated whenever new stuff comes along. To moderators: I'd be delighted if this thing could be stickied!
Please note that all these mods are only compatible with version 2.0 or later of the games.
GUI OVERHAUL MODS:
these are UI overhauls and as such, are not compatible with each other. You should install these before any other UI-related mods, as they'll overwrite any previous changes.
there are many other UI mods with small tweaks. However, EEUI Tweaks UI Mods Collection by AncientCowboy already does a great job of not only cataloging them, but also bundling them in a single mod which detects what skin you're using and makes sure they're all compatible with each other. I strongly recommend you refer to it in order to browse and install any of these smaller mods.
