WITHTLC Program is a very good start for a version 1.0 screen/web capture, but its early state of development doesn't warrant the price being charged IMHO. I grant you I have not played with it for hours but I found that when it crashed, it lost my organized library. There does not appear to be anyway to tell it to write out what it apparently is storing in RAM without exiting the application which is a painful way to do a Save. In addition, Little Snapper requires you restart it to select a different library. I am very impressed by the user interface.. and the way that the program allow you to capture a DOM element, but you can accomplish most everything Little Snapper does by simply printing out your web page to a printer driver that saves the output as PDF. There are an incredible number of these programs: YEP, SOHO, DevonThink, Notebook, Snapz, etc. - better yet, most of these programs can search for text keywords in the PDF.. Little snapper requires you to supply the tags and keywords upon which to search requiring you to do a lot more legwork. I expect the next release will support searching the HTML source it stores for text - but presently "search" only looks at the inspector data attributes.
