Allow to switch back to base account

[nosmicek]

We are using our base account also to deploy some common infrastructure, not only for user accounts and as an entry point to other accounts. So when switching between accounts, we need sometime to return to this base account and work there.
Currently I'm switching acounts with plugin, but for that single action I need to go to menu and click on "switch back".

So it would be great, if plugin also provides ability for "switch back" action.
My idea would be to have the base account also listed in accounts and on click it will do the switch back action as is in aws menu, or something like that. This behaviour could be configurable with some kind of switch as I assume not everyone would like to have it this way.
