Not sure if this is a bug or a feature, but it's been bugging me in the past few days because I use LFS Manual on multiple devices.

When I log in to LFS Manual in browser 1, then log in to the manual in browser 2, the browser 1 session is logged out.

Can multiple simultaneous login sessions be supported?

Had a look, but so far I can't really find any configuration options that hint at supporting simultaneous logins. I did find some similar reports from people with the same problem, but could not find any solutions. Seems to be a feature rather than a bug though, but it's debatable whether it interferes with the user experience :/
