Please make another version of this addon, one where Webnotes functions solely as notepad with tabs, without the potentially annoying Sites issue.. its not that it isn't useful to make a new tab note(s) that can be directly linked to a specific site (not just domain name unfortunately, which might actually make it less annoying).. but the way you have designed the addon actually just makes having such a feature more annoying than anything, like the fact WebNotes hides itself when tab/site url changes, and a tab note doesn't exist for that exact url.
Some particular sites don't even work, where It just says "Wait Loading...."
Anyway addon developer maybe take a look at Maxthon3 and perhaps borrow some ideas, also I don't believe webnote data is encrypted? a feature like addon 'Lazarus' offers good password/encryption functionality before a user can access saved information. Anyway maybe Webnote addon could borrow the same Maxthon3 header information that gets automatically added, keeping the tabbar, and instead of the sites method you have, just include an option for when a user makes a new tab, that particular site url is included as a link in the header info of a new tab... that way a user can delete that if its not required.
Personally Maxthon Classic had the best tabbed notepad feature, though another interesting notepad feature called Snippets was included in Epic browser as useful sidebar functionality a lot the features borrowed from the scrapbook addon, but it was a good mashup, that included searchable notes. I can understand reasons for not wanting to complicate the addon, but it has potential to be really useful if you could improve it more.
