Three little icons on top right?

This is a rough mock-up, but you get the usage.
I am sure that Shaun can do magic with ExtJS, or Sincha...

The vertical tab will only appear when entering the document "panel"/screen.

I like the new look, if the tooltips works there is no need to add a dropdown menu I guess, although for new users it is probably not the best way to understand how they works. BTW, is there any user guide?

Could be on mouseover, so it does not requires two clicks,
and instead of a dropdown menu, could be a button panel,
the 8 button in a vertical row...

Why not just do something like:

(button)Save and (selected radio)(/button) (radio)Add/Cont/Close(radio)

We just add the function to the button name based on which of the three are selected. It shouldn’t extend things as badly and may clear things up a touch.

As for the tooltips if title="" is defined then they should function fine in FF, but if only alt="" is set then they aren’t going to show as alt is a fallback if the images fail to load.

The title attribute is there, I’ve checked with firebug. I really like the new icons!
However, I have a problem with the main menu, I don’t see the link at the end because is too high and because the description is quite long.
