Hello,
Since Jira and Wiki are an important part of my work, I have to say that now. The new Design ... I've been really trying to get along with it since release. I am really sorry but it still feels uncomfortable. The old Design was more intuitive. Especially the Wiki, here I only use the search to find areas or pages, since the new design. The project design in Jira also feels uncomfortable. The 20 pages "new design" tutorial do not help. I do not have the time to read all that. That must work immediately. At least one could have kept, the option to switch back to the old design. Would be really great if that would be possible again.
I do not want to be mean, just some feedback. Sorry for my english :P (german)
