Top of screen - user dismissable information message
An app admin often makes small changes to its beloved Teamdesk app.
**The best way to inform users of that there is something new in the app** is not to notifie them by email, but by displaying a text info at the top of the page, with a close button enabling the user to dimiss the info.
That's exactly how it works now when you create a new Teamdesk app (cf. appended screenshot): as the app admin, you are prompted for a list of very frequent actions, and you can dismiss that info whenever you want to.
I think that would greatly help the unfrequent app user to figure out what's new when he reconnects to the app.
