Kimonote now supports optional comments on public notes. Comments can be edited by their creator and deleted by their creator or the note owner.
In addition, notes imported via RSS are now uneditable: this is to allow the imported note to update when the upstream RSS entry gets updated. Editing an imported note now reblogs it into your private notes, creating a copy that won't get updated.
The final minor change is that you can now attach a link to any note, public or private. Notes imported from RSS have their link set to whatever that RSS entry was pointing to.
