The Library
Rio's Library lives in the sidebar and holds your downloads, screenshots and other media, your spaces side by side, site tweaks and archived tabs. Open it with Cmd+Shift+L and drag any file straight into Gmail, Slack or Finder. Rio is a free, open-source browser for Mac, built on Chromium 158.

A screenshot, straight into Slack
You want to show a teammate a pricing table. Press Shift+Cmd+2 to start a capture. It lands in the Library under Media, at the top of Today. Drag it from the sidebar into your Slack message and send.
The PDF you downloaded an hour ago is under Downloads. Drag it into a Gmail draft the same way.
