Just investigated the problem: on my machine the bottleneck is definetly
the HTML rendering which is a good result for us, I think.
I will now try to adapt the UI so that ths project tree is rendered
progressively. However, if I encounter bigger problems I will move this
issue back in my time schedule because I have my first user test on
monday which I have to prepare in addtion to multiple UI fixes that are
outstanding.
Best,
Basti
