I have worked with EPiServer 6 new interaface this weekend and I do not know how many times I clicked on View mode instead of Admin mode button.
Please, CHANGE the new nice View Mode icon in EPiServer 6 that looks like the icon for Admin mode in EPiServer 5.
Show your support and reply to this post if you also get confused like me!
The appearance of the EPiServer CMS tool bar will be changed quite a bit before the Release Candidate and this is included in that change. It personally took me about 4-5 weeks before I got a >50% hit rate on the actual new admin button ;) and the team is aware of this problem.
