Wishlist: Rethink preset values / layout for the case when tool bar is too long

[Hachmann]

With the new gtk3 buttons, the tool bar for the text tool becomes too long for me to see the last three items (pristine Linux Mint 18 Xfce with a 4:3 screen, trunk ppa).

The drop down for letter rotation, where preset values are available only, isn't very useful (and the keyboard shortcut doesn't work with a German keyboard), as it doesn't allow for any fine-tuning.

Is it (somehow) possible to allow to actually enter real values into a real input field for these kinds of items in a dropdown? Or to make the tool bar wrap? Or make it scrollable?
Or allow to click on a button and then show the other half of the tool bar?

(The only workaround I know is: I can make the window larger and move it.
I cannot assign a different keyboard shortcut which can work with my keyboard because it's not available in the keyboard shortcuts list.)
