Hello,
Well, this is not really a session manager...
I've created this addon a very long time ago to solve a simple use-case => I wanted to access some of the tabs I have open at work from home and vice versa.
Anyway, currently the addon is outdated, it needs a huge upgrade.
I'm planning to build new version with better features in the future but I'm so busy with my other addons that I'm not sure when will I get to this. I wish days were longer...
Happy holiday :)

Best regards,
Juraj Mäsiar
