Unable to make nested lists
This may sound stupid but at some point in the DW life cycle the developers have taken out a way to easily make nested lists (ol, ul, etc.). Before you could be in live view, on a list element, and hit tab and it would nest the element properly. Now hitting tab does nothing and if you next a list manually and then try and edit that list in live view, it almost always REMOVES the nested list you just built!
I don't always need to mess with nested lists, but it just so happens I had a ton to do for a client and it was a PIA fighting with DW the entire time.
And this is present in the Windows and Mac versions, BTW.
