Make a MRU for the "Start Registrering Effort" in the system tray
When switching efforts using the system tray right-click menu, it would be extremely helpful to have a Most Recently Used list at the top with a couple of items, to avoid having to traverse a possibly deep hierarchy when switching between a few well hidden tasks. As for naming the items, I would personally prefer to use just the effort title without the ancestry and live with the possible ambiguity but others may have another view on that.
We’re not going to add, at this time, extra commands beyond those in the action menu, to the system tray. But I think you could quickly enough get what you want with this other request:

Please consider voting for that, thanks
