Ask HN: Handling multiple clients, VMs or desktop application?

I'm not sure if this is a valid concern. I'm experiencing this problem of having to log into different Trello/Slack accounts. Slack you can easily switch, but Trello I don't think so... also there is the "tech stack" for that company, the time zone... settings... Wondering if it makes sense to run specific VMs, it does make sense if you need a local copy of their platform. I was alternatively thinking about a desktop application... specifically with regard to keeping track of events/time zones. I heard of Electron, I'm a web developer but can't develop desktop applications...
