Re: [Lxde-list] Consider switching back to GtkRcStyle conforming way to handle panel background.

Okay.  No problem.  We do have a fair amount of time while we are waiting for the translation work to be more complete, and we are not on a strict schedule here in any event.  If you were to check the forum, people are delighted with what is in SVN now, and I have added a few easy things as they have been brought up there.  I have closed most bugs within a day or two.  We will most likely get these other things solved fairly quickly if we work together.

It is also distressing that your proposed solution to what is probably a simple bug is to totally replace something.  It is also distressing that the problem is characterized as "yet another regression".

I freely admit I don't use theming and I don't understand it well.  I think if you were to take out the mechanisms we have and replace it with something new that users have to understand in order to do what they can do today, they will be unhappy with your changes.
