Yeah that's the first thing I thought of, especially if it's possible to pause and inspect/introspect the DOM and code, that would make debugging client issues much easier.
Although just capturing user session would already be nice, better than forcing people to take videos of their desktop (and with a bit of luck the file would be much smaller)
Exactly. I'm imagining a world where I tell a customer to use a Chrome add-in that automatically starts recording what they do and uploads it to me and I can see what is going on.
Even if not that wonderful, just the ability to have QA or fellow developers send me a file that I can analyze instead of tying up their computer would be wonderful. Especially when working with remote co-workers.
The problem with video is that I can't inspect their DOM or their console.
Use Selenium and whatever host language you want to pause, introspect, etc (example, Java's sleep and use jSoup to parse DOM after grabbing it with Selenium's getBody() )
Selenium's no good, and it's even worse for user recordings: it only stores activity, so if the issue came from e.g. a mishandled network glitch, it won't be recorded.
