Group mode for checklist

Dear checklist-plugin-builder,

First things first: awesome plugin, thanks a lot!

Second, we have our students work in groups regularly and it would be great if they could have a shared to-do list using checklist. Thus, one list for a group, where any member can mark something as complete, automatically marking it complete for other group-members.

This is currently not possible, is it? If not, this is my feature request, I hope it is possible. If it is not too hard (I am a programmer, but no Moodle-expert), I could also look into myself with some pointers.

Thanks a lot in advance,

Frank
