Does anyone know of any 3rd party add-ons for OS X that allow you to 'snap' or align any on-screen window to the other windows? I'm looking for a system-wide add-on so I can use this feature across all my apps, collectively aligning their window edges together to try and keep things tidy. I keep thinking someone must have developed an add-on that does this but all my searches have turned up nil. :O anyone know of anything? Thanks in advance!
