Calberts, Blink is good. You can also open files even when they are loaded, to say ImageIntegration, by double-clicking them. I also recommend the wonderful SubframeSelector script.
Juan, here's something I'd like to see added to Blink. Depending on the file naming conventions of data, it can be a nightmare to delete bad subs from the folder. Blink should allow us to permanently delete, or at least move (not copy) files directly. Just today I found myself bug-eyed trying to match the names of bad subs (i.e. NGC 6744_Blue_20120513032927_900) between Blink and the image folder, in order to discard it. Even using Windows Explorer's search feature made for a difficult time. I am going to repeat this in Wish List, please feel free to delete it if you wish to avoid duplication, and thanks very much PTeam!
