Skim.app Hack(s)
This contains various hacks to Skim.app.Auto Reload of Changed PDF's
I am using Skim.app for previewing PDF-files that are autogenerated from my LaTeX source. The main author of Skim.app apparently does not think that it is Skim.app's main purpose, so he is reluctant to include a common feature, namely to have Skim.app auto reload PDF's when they change on disc without requiring user confirmation. Although Skim.app only requires confirmation the first time a specific PDF changes, it is still cumbersome to do it the first time. The main reason the author does not want this feature is because it will loss any unsaved notes you have added to the PDF (notes are apparently the main purpose of Skim.app).
