Not switching designs
After selecting a design, you can not select another design for the same project --> If you click the other design, the url on top changes to the proper name, but the view is not refreshed. It is still stuck to the previous design. In order to select another design, I had to go back to select the project again and then select a new design. If you don't know about this bug, please test with any topic with more than one design and you'll see the problem.
