In my opinion, among open software developers there is not much attention given to the GUI or how it is used. With very notable exceptions of course, Blender, Ubuntu, VLC, and maybe others I've not used yet.
Although GIMP, Inkscape, Eclipse, and many others, are way behind their commercial or proprietary counterpart, Photoshop, Illustrator, Xcode, VisualStudio, regarding usability and UX.
Given that usability reflects in how one accomplishes a given task in an efficient way, I'm curious about how those issues are approched by the open software developers/community.
Is an issue regarding usability as important as solving a reported programming bug, for instance?
Are there team members with experience in UX, GUI design, and usability?
Is there some platform similar to that used by most bug tracking websites, but focused on UX?
