Save commands
Open Fast Actions from the Pages menu in the panel header, type a name and a command (like npm run build) into the row at the top, and press + to save. It joins the list, ready to run from the notch any time. Delete saved actions right from the list.
Track command status
Run an action and its row shows running, then succeeded or failed, and a failed run shows the last line of output so you know what happened. A long run can be stopped any time. It's the fire-and-forget middle ground between "open a terminal for this" and "hope it worked".
Shell environment
Commands run in a login shell from your home folder, so your PATH finds the same tools your terminal would: npm, node, pnpm, and the rest. Need a specific project? cd into it as part of the command. For anything bigger than one command, a whole agent workspace for example, that's what Views are for.
