Works great and as easy as expected.
Very cool and quick.
One thing I would suggest to make the handling more interactively. Just a visual reaction when clicking (and copying to clipboard). This could be a highlighting (brightening) of the value numbers or a short framing/background coloring with the click. I don't know if lokasenna's library offers something like that. The best would be a short massage (no pop up) or an icon which shows that the numbers are copied to clipboard.
Beside that its very cool tool.
Many thanks for that.
