Check and update node status (e.g., opened, visible) when opening historymap

Now historymap would automatically load the previous session and some of the node might be open.

To be consistent with the current session, better not to load node states from previous session.

In case the user wants to restore the previous session, maybe add a button to highlight nodes in the previous session (opened) and let the user decide which nodes to restore?

I agree. Maybe just a button so user can restore all the opened tabs from the previous session? Selecting which tab to open individually would be the same as clicking the nodes in historymap?
