About the track editor, while this would be amazing, I think (and I can be wrong) that what most people want is the ability to add new tracks, be it through a track editor or just creating the tracks in other software and being able to import to LFS (coping files to LFS directory like in Assetto or whatever), not everybody has the knowledge or time to create tracks. I think the track editor route is more complex (although it was the chosen way for car mods).

I think the game is crying for more variety and the possibility of driving on new tracks would add to replayability and attract more players (very much like there is more people playing Assetto Corsa because of variety than the "more advanced" Competitzione counterpart). Should be priority #1 in my opinion.

Another thing people realize when watching lfs videos on youtube is that "car ping flickering" and how bad it looks. Also makes watching replays a bit painful, especially in cockpit view when "look to where you steer" is enabled (used a lot for drifting). I thought it would be fixed when they increased the packets per second but it didn't. Looks like an easy fix, but i'm not a programmer so go figure...

Also +1 for engine sound improvements.

Just wanted to give my opinion so don't get angry at me
