If the screen goes to sleep are the widgets suppose to refresh after it wakes back up?
Yes, it should, given that connection to server was restored. There is no notification if connection is lost yet, but it should be added soon.
Is this already done?
A couple of times I noticed that the data on the panel is not correct, it turned out that the connection to the server is not installed. It would be nice to always see the status of the connection.
No, not yet.
