To be clear, OpenWRT is a great OS. The UI is a bit old fashioned, existing functionality could be exposed more cleanly, and the terminology could be more intuitive.

This is basically what gl-inet did! You can compare how they expose functionality. Of course, it’s limited, but eventually the remaining features in LUCI could be incorporated in the same UI.
