Switching to Skim for PDFs
I often have a ridiculous number of PDFs open. I like to have reference materials handy, and it's nice to be able to have two or three PDFs side by side on my large monitor so I can compare information.
My habits are too much for Apple's built-in Preview app. If I try to open more than 10 documents, it keeps adding them to an existing document window, so I have to take the extra step of moving the document to its own window; and if I open a LOT of documents, it'll start to crash now and then when I bring the app to the foreground.
