Replaces built-in html editor with the one of your choice.
I created this add-on because I spent lot of time copying from Anki to vim, editing, and copying back.
It allows you to specify your editor of preference.
In Anki 2.1, menu: Tools/Add-ons, click Get Add-ons..., and enter:
704320065
Restart Anki to finish installation.
You can change the editor by clicking in "Config".
