The actually used UI is still good but not perfect. The codec configuration could be better. I make my set of options and save this as named preset like "VK2 nV HEVC@M10-HL5.1 2160p25 15-30MBit VBR+AC3 2.0 192kBit". You can drag&drop this in AME over the project files or choose this from the project line. After that you can modify special parameters like the bitrate.
I think there is something out there what could be treated as good: The codec configuration of "MeGUI". For x264 there are 5 Tabs. Only in case of a checked "advanced settings" the 4 last tabs will appear.
Something like that?
