I wanted to submit a feature for kde that would allow users to set the application style to a qstylesheet file (style.qss for example). This feature would greatly increase the amount of themes available for KDE, make it possible for users to tweak themes themselves, and make it easier to include custom icons/images with themes if necessary by using the url() function in the stylesheet. It would also make it easier for experienced developers who can make KDE themes in C++ to make multiple, more complex themes in less time. The feature would also be very easy to make and would probably take less than 1 Megabyte of total storage.
I originally wanted to submit this as a project in Google summer of code, but I missed the deadline for applying. Who should I contact to get approval for this before submitting a pull request?
