I still fell this thread should be split from this point on in a separate and general icon themes discussion related thread:
https://forum.freecadweb.org/viewtopic. ... 20#p287840
And the original thread to be moved to UX/UI Design forum section. If that won't happen, sorry Pablo, for being off topic in your thread. If and when you decide to proceed with your work, just open a new dedicated thread in UX/UI forum section.
Anyway, what i would like to see next, is to get some confirmation, this process isn't too complex:
https://forum.freecadweb.org/viewtopic. ... 30#p292101
If you two could confirm, creating such demo icon theme pack is doable on your side, that would be great.
