I'm looking for a control like Outlook uses on the left hand navigation panel. It has a tree with numbers to the right, representing things like "number of emails unread". Is there a control like that for ForeUI or maybe even an accordion (with the number label)?
I think the Tree element is most likely the one you need. Althought the lack of action to directly change the text of Tree node, you can still embed a text label into the tree node and update the text label when data changed.
