Indicate your active session account in reader/comment view

I find myself in a situation where I publish leaflets to multiple accounts. When I go to leaflet.pub I can log out of one and into the other (tho an account switcher for multiple sessions would be great). However, when I am reading someone's post, and especially commenting, there is no indication of which account is signed in. I only realize which account I am posting from after I have posted a comment and my handle appears next to it. A signifier of your active session identity, even better a switcher, would be helpful in any context where I am creating records, including the reader view where I may subscribe to a publication, and the comments pane.
