How can we improve WHMCS?

Hi,
I want to have the ability to choose who can see the notes in the Staff Noticeboard by department.

So When I add a new note I could choose which departments this note is relevant to - so when posting a note relevant only to support I
can choose only the support department but when posting something that relevant to support and sales to be able to choose both support and sales departments etc.

Now I can add note that will be visible to all of the departments and that causes a load of not necessary notes in the Staff Noticeboard.

I want each department staff so see only the notes that are relevant to them.

Thanks!
Ram
