just at the moment I orphaned abakus.
Abakus  is still based on qt4. There's an already long open bug  about open work in coordination with upstream to port it to Qt5. I remember found some patches somewhere (lost link) tor a qt5 port, but do not find them any more. Further, upstream should be checked if still alive and poked about a new release with the qt5 feature. unfortunately I don't find currently enough free time to do that work, could maybe someone else pick it up and talk to upstream?
I wonder if it's just me or others also have problems with performance
of Pagure. Pagure is always slower for me than e.g. Github, but it's
bearable. However, there are times when I have to wait easily 30-60 sec
to load a page which makes Pagure almost impossible to work with.
