Conceited Software developer here. Clips 1.5 is getting a lot of new users in a really short time, and I just want to let you know that we're reading the issues some of you are encountering. We cannot fix everything as fast as we'd like, but we're taking every feature request into account. Bugs such as memory leaks, happening under some circumstances, will be fixed in the next 1.x update - which we'll release as soon as possible after thorough testing has been completed.
As far as documentation, the screencast on our website is a good introduction to using the most important features. We're also writing a user's guide and it should be ready and available on our website by the end of the week.
The most often asked question has to do with licenses and whether or not they're tied to a single computer. This may not be crystal clear in the application in its current version, but I'd like to clarify: a single user license (like the one you get in the MacHeist bundle) is valid to be used at the same time on two Macs. Which two is up to you. Could be your desktop and your laptop for instance. You can find more licensing related answers at http://conceited.net/wiki/activation_faq
Thank you for your interest in Clips and we look forward to your continued feedback, helping us make Clips work better for every Heister.
