I don't want to scare anyone, but I have found the following quirks on my own and I have to warn you about them in advance.

  1. When you close the measurement tab, the main tab crashes - though it's annoying, there's nothing wrong with this. I have the suspect bugs for this on my kill list :)

At this moment there's only one problem I've found, but feel free to tell me about any oddity you encounter via the email found in the footer of the page.
