Looking for plugin: Preview TT/quadratic outlines

Hello, before I unnecessarily write something myself, is there a plugin that visualises the current drawings as it will appear in a TTF export? The conversion to quadratic outline sometimes has rather drastic consequences to the outlines and I would thus be interested in being able to preview it directly while editings.

Thanks for any pointers!

Show TrueType Curves

No idea why I didn’t find that in the plugin manager. Thanks a lot.
