I am just testing the new prerelease of Plone 5 and I am annoyed by the action bar on the left. It does not fade out so that the first characters on pages and in forms are not visible.
It is supposed to push the content of the page over to the left so it doesn't overlap with the page.
After a smooth install I couldn't beleave what I was seeing: There has a froggin' lotta work been done, I am very much impressed of the progress. Was clicking anything I could grab forquite a while and besides of the above mentioned issue didn't notice any other annoyances, just delights (especially about the edit-bar, folder_contents and collections). Huge thanks to all progressers!
