Switch Glass - A Configurable Application Switcher with Per Display Settings

If you are one of those Mac users frustrated by the fact that the default dock is only visible on a single display, or you don't like the way it deals with hidden windows, or maybe you wish you could hide certain apps, you might want to try Switch Glass, an app by well known Apple podcaster, developer and writer, John Siracusa.

Switch Glass lets you configure a (hide-able) floating app switcher for each display in your setup.

• Visibility - Set it to be visible, hidden or auto-hidden/visible depending on mouse position 
• Position - Choose from eight positions on each screen 
• Orientation - Horizontal or vertical positioning 
• Background - Choose from four different backgrounds including dark mode toggling 
• Styling - Three different corner styles 
• Icon Size - App icons can be anywhere from 16 to 256 points in size 
• Icon Spacing - Adjust from 0 to 100% of the icons sizes 
• Margin - Adjustable around the switcher itself 
• App Sort Order - Apps can be sorted by name or launch order

You can customize what clicking or shift clicking on an app does, with options to bring all windows or a single window to the front. Using option+click will hide the current front app while opening the app you click on. The app switcher has a context menu for each app and supports dragging items to the icons to open them.

As would be expected from a developer known for having exacting preferences in his workspace, you can fine tune almost every element in the app. Switch Glass is $7.99 on the Mac App Store.
