Got an unrelated feature suggestion: a fractional-unit grid for UDMF.
Backstory: I'm in a spot where I'm getting nodebuilder precision issues in a map and need to quantize a mass amount of vertices somehow. The "Snap Selected Elements to Grid" feature is exactly what I need, but 1 unit is still a bit too granular for most areas. Being able to snap vertices to 1/2 or 1/4 of a unit would probably save my bacon here.
[BTW, since I haven't posted here for a while, just wanted to say that the latest versions' enhanced sector splitting stuff is mighty cool. Takes a bit of getting used to, but being able to drag A over B and have A still be intact is hella useful. Props n' whatnot.]
[Double-BTW: I quite like the new texture browser. Folks iffy about it ought to try using long texture names sometime.
