I started using SnagIt a few years back while working a job at Accenture. We primarily used the tool for grabbing development errors to share back and forth with the team.
Recently I’ve begun using SnagIt 8.1 This is a significant upgrade to the version I previously used. The new dashboard they have which allows me to select what I want to do with the output image on the fly which is a change from previous versions. The other thing that has proven to be really handy is the option to select an entire web page. This allows me to grab a screenshot of of a full page, no matter how long it runs. We do a lot of mock up for customers and this functionality gives us great flexibility
