(again: sorry for my english :-) )
I start yesterday with this (great) program. I was lucky to find very fast the "Customise Toolbar..." but then: there are only a few functions, I can drag to this toolbar. (I can not see the rules, what is avaiable or what not...)
Why not all of the normal Menu? I, for example, needs often "Open" or "Export" or "New from clipboard" ore the simply "undo" and "redo". Yes, I can use the keyboard or the menu himself, but there is a good reasing for a Toolbar... when I can use it with my own workflow.
