Float on Top
Floating a window on top is a feature of many paid apps on the Mac App Store. Orion for macOS has it built-in for free.
- While viewing a window in Orion that you want to float, click the Window menu.
- Click Float on Top or type Control-Command-U.
The window will now float on top of all others. You can use the same menu choices or keyboard command on the window to disabling floating.
