If you ask... Here are my 2 main wants and some more that are nice to have as they improve the overall experience:
-Enable camera2 API for RAW support. (Plan to use it with Footej camera by a Greek developer by the way)
More info: http://forum.xda-developers.com/le-max-2/help/testing-camera-2-api-t3422364
-Add A.R.I.S.E. audio mod includes aptx HD, LDAC for quality wireless streaming (pretty critical for a jackless device!) plus more tricks & tweaks.

-Add xposed (optional)
-If you add xposed you can also add Android N-ify module. (optional)
-Add substratum theme engine. (optional)
-Add Action launcher for android's 7.1 shortcuts. (optional)
