Looking for an app to run commands/long-lived processes easily

Wave Terminal used to have a feature called "blocks", so you can run scripts or command line stuff and they appear as a "block". When you have many blocks it is useful because you can expand/colapse them, see which ones ended or crashed, restart them, clear/delete the block, etc.

I'm looking for an app that does more or less the same, like helping manage long-live processes without the need for multiple terminal tabs or panes, where I can collapse all them because I don't care of the output, just know if they are running or not.

After trying I think it just doesn't exist heh, but I hope someone has an alternative! Thanks
