Display and remember tab database

I select database A(table 1, 2, 3) after select database B(table e, f, g). And i select again database A but It don't remember tab of database A(I was selected before). I think new version update it (remember table other database selected)

Thanks!

Query tabs are not in any way bound to the database you have selected at some point. They are not even bound to a specific server session, when you have multiple sessions open. I guess that's what you expected?
