I've been trying to find some ROMs which boast amazing customisation (like CM back in the old days).
Resurrection Remix is good, but the lead dev quit and it hasn't been updated to Android 10.
CarbonROM seems to boast that it's all about customisability and it does look like it has much more features than most other Android 10 ROMs available: https://youtu.be/SHbYchQKj2I?t=60
Someone just needs to make a stable ROM which combines every feature of every other ROM. Easier said than done!
