What is new in Dusty 2.1.0

Dusty now frees memory too. Not with a "boost RAM" button that runs `purge` as root, but the way that actually gives memory back: by showing which apps are holding it and quitting the ones you are not using, after you say so.

**A Memory screen**

- **The real picture.** Memory in use, split the way Activity Monitor splits it (apps, system, compressed, cached files), swap, the last hour as a graph, and memory pressure, the one figure that says whether your Mac actually needs more.
- **Apps, not processes.** Every app's total counts all the processes working for it: Chrome's helpers, Safari's web pages, the tools a terminal started. That is exactly what quitting the app gives back.
- **Idle apps, already ticked.** Big apps you have not used for an hour are suggested. Dusty knows when you last used each app because it notices when you switch. Terminals, virtual machines, calls, and anything playing or recording sound are never suggested.
- **Free up, with a way back.** One tap quits the suggested apps after a confirmation that lists every app and its memory. They quit the way ⌘Q quits them, so anything with unsaved work asks first. For a few seconds afterwards, **Reopen** (or ⌘Z) brings them all back.
