Well, copy-paste usually does the trick for me. 🙂
Generally speaking, people develop their theme in a local installation, and have theme check running there. So they can change the theme files and just re-run theme check immediately.
I’m not a developer so the export of the information word be great so that if there are errors in the theme I could then simply pack it up and send it to the developer. A screen capture could get to be large and some email host’s would not allow the image to be sent. So, by creating a file that would be a lot smaller in size would have a better option of getting to the author. I agree, if it’s a small screen capture it wouldn’t be much of an issue.
Just my thoughts from a NON developer……..

This is not a plugin for end-users. It doesn’t tell you anything of use.
Theme Check is meant for developers who are creating a theme. If you’re not a developer, then you don’t need this plugin.
