Hi. Great plugin, thank you so much.
Whenever I open ZeNotes settings when I have a collection or sub-collection selected that has an ampersand character (&) in it, it errors with:
SyntaxError: An invalid or illegal string was specified.

The error is thrown twice, and then it goes into settings, but the Tag display and Tag sorting blocks at the top of the dialogue are blank.

Similarly, ZeNotes list on a collection looks like this....

Whereas I replace the ampersand with 'and' I get the right table:

It's not a biggie, I think you are blocking some dangerous characters. I tested and also got the same on the less than (<) symbol. I understand why but it is useful to use the shortcut to keep title lengths down. Probably just an encoding fix?
Thanks
