So I built my own IDE around that workflow. Terminals are a first-class citizen, every project stays alive in the background with visual statuses. Close the workspace and come back weeks later, everything is still in its place. I've been using it for weeks and it's a big productivity boost.
The idea is a super tight core with a robust extension SDK. Features are built as extensions and are optional. Extensions can easily be built with a coding agent and shared in a registry. All open source.
There's many great TUI apps that have similar features, but this is built for someone that loves VSCode. Please try it out and send feedback.
