I wish you could tell it to not load some *.py files (they aren't part of the plugin and are included so I can use additional functionality).
The plugin's unload_handler() isn't run when quitting the app, which isn't very nice. @atexit.register also didn't work.
The plugin also won't reload when the source is changed. At least when there is a symlink in the Packages directory pointing to the plugin folder.
But the editor seems nice and will be a good editor after some UX and API work.
