No not yet. Tbh, I have not toyed with UEFN much at all. Tested it Day 1, but after getting error messages that both Octanes and Hover Boards (my two favorite items) were unsupported I decided to focus on Creative 1.0 until I UEFN comes a bit further in its process.
Thought a bit about the topic of intent (that of re-allocating unused binds) and concluded that just adding one re-mappable bind would be an amazing first step. I personally make it Sprint. If I my map needs sprinting I just make make the map smaller (similarly if I need mantle i just add stairs, mobility items or gravity).
I will dive deep into UEFN soon enough, but at the moment still waiting for publishing permission for my 1.0 maps, been waiting a week.
