Today i tried Bio7 1.7.1 with the new Eclipse 4.4M3 platform and it didn’t look bad. There are some minor UI bugs/defects and missing implementations (detached views, e.g.) but i’m quite confident that these bugs will be resolved soon by the Eclipse team. At all this is huge improvement to 4.3 which was not usable with my RCP application. Here a first screenshot:
As you can see some controls and menus are not in the right place. But at all 4.4 will be a huge UI improvement.
