Additionally...

• Why are there 'max' values and sliders, and no unit chooser? This seems severely limited.
• Close subpaths doesn't only close, but also deletes nodes at the ends - a 3 node path becomes a 2 node path. But it is closed...
• Using linebreaks to add a space in front/after a description text is a questionable technique, as those show up in translatable strings. We have spacers for that.
• Keyboard shortcuts should not be part of the text as they can be changed by the user.
