Problem: If you are working with more accounts, there is no simple way to switch between your accounts without logging out and logging in with other credentials.
Proposed solution: Add an option to log in to more than one account at one moment. By clicking on your user name, you should be able to switch to another account. I think that this should be restricted to only few accounts (max. 5 [?]). The security aspects should be taken into concern.
Who would benefit: users with multiple accounts (bot accounts, test accounts, WMF/WMXY accounts, employee accounts...)
More comments: The actual workaround is to have more instances of the web browser (or more browsers, e.g. one account in G Chrome, other in Mozilla Firefox). I perceive the opportunity of switching the accounts as a standard feature in 2020s.
