TYSM!!! if you have any problems, feature requests, etc, feel free to send me a DM/email. always happy to figure out how I can add more value to it.
to answer your question: context switching, basically. one of the big problems my ICP has with most todoapps is that they work for doing one "job": school, accounting, sales, software, etc. this feature aims to help solve that problem
(yes, it's effectively just workspaces :p)
