Massive UI overhaul:
https://forum.corona-renderer.com/index.php/topic,942.msg44187.html#msg44187Corona materials/Texmaps now have their own category. The main render settings dialog was redesigned - less used values were removed to new System tab, and Actions/Postprocess/Progressive tabs were merged with it - the idea is that everything one needs for basic render setup is now in a single tab.
Also when opening one tab, all other tabs are closed. You can use right mouse button to open/close multiple tabs independently as before.
Build will be up in minutes. A lot of testing will be needed. Any feedback is appreciated.
edit: build is up. Next step: UHD cache UI simplification
