It would be so perfect to have those elements in the Customize Toolbar, so one could place them in the toolbar for a fast access: - Show Line Endings - Show White Space - Line Wrapping - Show Line numbers - Hide/show menu bar (or even more perfect: menu-symbol, like in Firefox)
Or, is there a tutorial how to add elements in the Customize Toolbar?
By the way, the White Spaces are too small and nearly invisible.
