A coworker has been struggling with this problem.
The desired result is an installable plugin for Notes that will add a button emails with attachments that will let users save the attachment to a document management system.
Finding documentation on doing this for Notes has been an uphill battle to say the least.
Writing the actual java to do the work isn't a problem, but figuring out how to extend Notes is.
So, is there a way to add a button/icon to the toolbar, or is it just a matter of adding a new toolbar? If we add a new toolbar then can we make it only visible (or just grey it out otherwise) when no email is open?
