Upon first selecting the toolbar option, a choice dialog may present itself with the different style editors. The choice could be saved into the appstate, and allow the user to skip the choice dialog if they want.

The dialog itself is trivial, but this would also want a Settings/Preferences window to adjust the choice later. ProffieConfig already has AppState to handle preferences, but no UI to actually manage it.

Both are fairly straightforward though.
