Hi,
I am sorry to say that at this moment there are no plans for a Notes UI, as a lot of the functionality would be very tricky to replicate in the Note Client, especially the portal and navigators.
I hate to say that we cant do something to the first person that responds, but, although it isnt part of the main project, if someone is prepared to look at creating a Notes interface for OpenIssues then we could look at putting it into a later issue.
