I don t think Plex pays enough for me to consider it.
I have a bit of experience in managing an IT Company. That is probably why I have a bit a different view then the “I want it that way. Why is no one giving me what I need right now?!”
If you suspect Illuminati working with plex through me to assassinate your wonderful, enriching idea, I won’t stop you from believing. 
on a more helpful note. I think this is what you want: Allow GUI design by Plex members!
