I spend most of my day context-switching between completely different workloads — and tab chaos is a real productivity killer. Workflow01 solves this cleanly.
The single-window approach is the right call. Most workspace extensions spin up separate browser windows which just clutters your taskbar and your alt-tab list. This one swaps tabs in-place, so you stay in one window and just change context. That alone makes it worth installing.
Minimal permissions (tabs + local storage only), no external calls hopefully.
