hi, I've been having a play with the icons some more.
this is a mix of the icons by jendrzych & the tango icon set & custom.

as you can see, i added numbers for the unused maps, it can be useful.
there is a new View icon & fresh 3d manipulators that have the colors consistent with the manipulators in the 3d view.
the playback icons have been revamped & the python icons constant.
if jendrzych or anyone finds any of this useful, go for it!
here's a Beveled Button version,

this is quite interesting.
i have tested this with many themes & it can look quite good having this style.
anyway, if the icons are being revamped, it's good to throw around some ideas.
thanks.
