Hey - spent a lot of time in this world (solution / sales engineer, technical account manager to many clients), and thinking about this same problem.

Even experimented with per-client Linux users. Per-client calendars & routines. Per client knowledge-base, etc

Very curious to see what you come up with.

Reminds me a bit of qubes OS with different motivation.

This is awesome. I always have imagined my computer being well, my desk. So far I have to live with a bunch of i3 screens I name after whatever I'm working on. I'd love to be able to page through the bench to flip to a task. Unfortunately with apps going so mono-windowed (slack, etc) it's harder to do. If I could just say have my slack window for this client, with their docs, proposals, database, whatever up, that'd be sick. I love the idea thank you. good luckl
