Feature requests :
A ruler tool to measure distance in doom units between two grid points. example : http://syr.taaaki.za.net/tdm/random/ruler.png
Things to consider :
Would be nice to leave them out when swapping tool
Maybe add a 'path' mode for measuring multiple sections.(0->1->2...N)
Would there be any use in allowing textures to be aligned to them?
I'd like to "vote" for this feature. When figuring out the hide_distances of entities it becomes extremely tedious to always use temp. brushes to do measurement, esp. as these work only in 2D.
