I thought I would let you know some things that will be in the next release.
I've decided that the current manage notes page is a horrible interface choice and will be switching to a more hotmail like look. ie: more condensed with links to full blown editing, checkboxes to select messages that should be deleted, etc.
Email support so that administrators can be notified when a notes is added. Optionally a cronjob script that can be run once every X days to email the number of queued messages (probably a more convenient way).
Possibly an easier to customize layout.
A customizable list of acceptable HTML tags.
