Please configure the user interface of the Clipboard to automatically open the panel for VIEW ALL MISSIONS when you click MISSIONS at the first level of the Clipboard.
As it is now, you click MISSIONS at the first level and you get to the Missions menu and then have to click again to see anything useful. Changing this might make joining a mission just a skosh more attractive. Just as an example, if you click HANGER at the first level Clipboard menu, the panel with the list of planes and vehicles unfurls automatically.
