I know what you mean.. I heard it so many times from themers .. I Never did themeing before. started not long ago so I don't
have what to compare with.. I'm not even know what I'm doing, coding wise,I mean
.. Just took the time to look at some other themes codes and red a lot of instructions on the net.. about engines and stuff. all the rest is hard work with trial and error all the way..
Funny as it sounds, I tend to understand the Gtk3 part better..
