If you ever tried to hand-code a GTK+ theme, you will probably like to check out a new Gedit plug-in called Cossa by Carlos Garnacho. The plug-in helps creating new GTK+ themes by providing preview of GTK+3 widgets.
Here is a short video demonstration provided by the developer:
Right now the code is available only in Git repository. You can easily add more types of widgets to preview, here is a short manual how to do that.
Hey. Excellent stuff! My guess is that many to-be theme artists are deterred by the lack of tools so this is certainly a good step in the right direction.
Nice work!
Well, there already were tools for testing, like GtkFactory, e.g. but there was lack of easy update of changes, IIRC.
