Shared mails

[Grey]

Is it possible to add share function to mail accs? or fast switch for shared accs
Veru useful for some ppl.

For example.
I have 2-3 accs on mine server (1 work mails 1 friends 1 .... etc)
just want to have option to share acces to them.
something like top bar with list of shared mails to acsses them w/o logoff and login to another
