This little mod allows you to add Usernotes directly from the postbit when browsing a thread. It uses Ajax to post the usernote, so your page isn't refreshed at all.
You can post the note then carry on reading the thread without being disturbed.
Upload a couple of files and install the Product XML - Check install.txt for detailed instructions
Below is a step-by-step guide of the mod in action.
1) User starts off with no usernotes
2) Click on the dropdown when viewing a thread to add a new usernote
3) Enter a usernote
4) Click ok and carry on reading the thread (no page reloads or extra screens involved)
5) In the users profile it now shows that they have 1 usernote
6) And here is the usernote we just added
