The recent MPU episode (#471: Menu Bars, Docks & Startup Apps, Oh My!) reminded me that one can customize the Finder Toolbar, allowing for another quick method to access most used apps, especially with drag-n-drop .
Great tip, @Cowpi. I’d almost forgotten about this one.
It’s worth noting that other things can be added to Finder’s toolbar using the same technique (⌘+drag), including files, folders, and smart folders.
