Is there a way for one Cocoa application to attach drawer-like windows to another application? We might for example want a terminal drawer that followed around a particular Finder window.
There is a program called DTerm that opens little transparent windows over Finder windows, but one might prefer persistence.
You may want to checkout SIMBL. It allows you to write nifty bundles that are loaded into the application your targeting. If you go along with it I’d reccomend using class dump to gather more information on the application your working with (although Im not sure it would work with Finder)
