Panelet groups two to four apps into a single resizable layout: drag the dividers to adjust proportions, then hide or bring back the whole workspace with one keyboard shortcut instead of hunting down each window individually. It’s a native macOS utility, not a screen-recording or remote-desktop tool, and Panelet states plainly that it never reads what’s inside the apps it arranges. It’s a one-time purchase, discounted to roughly US$1.75 during early access.
