Path to perfection... ( a plea for feedback )

“Perfection is reached not when there’s nothing left to add, but when there’s nothing left to remove.” - Antoine de St. Exupery

I have been frustrated with the UI of Flo now for the past week. As mindmaps grow larger, I keep feeling the UI get crowded. Now maybe there is nothing that can be done to fix this. I don't know, but I wonder what you in the audience think. I feel my input is now rendered useless because after 2 years I am so trained on how it works I don't notice the UI braindamages.

So can anyone provide me with mockups of a cleaner interface? What would you remove from the toolbar and hide in a menu? What would you do with that "Property" editor on the lower right hand corner? Is it better served as a floating dialog? Is the title editor better served as an in-line editor on the mind map? Or should it be on a dashboard of the main UI. Should the top toolbar be smaller?

Also for any of you who are interested I have subversion opened at: http://svn.geiseri.com/svn/projects/flo. You will need at least Qt 4.3, perl and HunSpell's development libraries installed. On windows I have included HunSpell.
