ImpUI patch 7 has been available on mod.io for a while, but here's an alternative link ahead of release.
Please remove any patch 6 or below versions of ImprovedUI before running patch 7. We know there's going to be problems with it, that are "fixed" in this mod, but so much has changed under the hood I've practically rewritten the mod.
There's no need for a "ImprovedUI Assets" any more. Custom Action Resource support is all tied into the one file, because many of the fundamental UI restructuring has to be done once unless it becomes unmanageable.
Warning - We are still working out the kinks for modding the UI in the new Patch 7 process to prevent conflicts between mods. Expect there to be issues when running multiple UI mods in tandem.
Edit1 - minor fixes (feature icons in controller cc, custom action resource in tooltips and respec/magic mirror ui on controller)
