For TinyMCE 3 drop down menus for functions now being handled by buttons. Instead of separate 'bold', 'italics', and 'underline' buttons for example, have those buttons available in a drop down menu under a 'styles' button. Or perhaps a 'text' button giving as options styles, justification, fonts, text properties (extended, compressed, shadowed), etc. Basically, group functions together and do a drop down menu for that group. The table buttons for TinyMCE Advanced really call out for this. Would save space and eliminate the need for extra bars.
