In this latter experiment I tried out radial projection with some targeted projection:
The current version contains a couple of basic projections (horizontal, vertical, target, radial, parallel) and means to deal with projection targets (set, cycle). As a bonus I implemented projection preview.
The default hotkeys have been bound to number keys (not numpad!) spanning from 1 to 7. They are configurable at src/js/conf.js. There are some other goodies there as well.
I suppose I will revisit symmetry functionality next and then move onto layers or something else that's fun. Feedback and experiences on the feature are welcome as always. I probably should try to host the app somewhere but for now checking out the repo or downloading a tagged version (v0.39) ought to do.
