You should charge for the basic plug-in as well as the premiums. I used the free signup.com app very briefly. Now I pay $150 a year because I want more than the basic functionality. I could easily justify paying at least that for a pro version.
Donations aren’t a great way to go with non-profits. It’s easier for them to justify a fee than a donation. (go figure).
The two features I would most want: 1) one more field for each task – a text field that I could use to add a few notes about that task. 2) ability to someone to easily add new sheets who isn’t a programmer.

I’m really impressed with this.
