Hey Oliver,
This is actually coming very soon. Depending on how long you've been a customer you might have noticed we've been rolling out changes to all of our marketing and documentation pages (revamping the style and making them mobile friendly).
We're currently in the middle of a revamp of the LimeLM interface itself. It will look a lot nicer and it will be more useful (put useful data first).
Among the changes are the ability to add custom columns to product key and verified trial lists -- giving you more control over how you view and process your data.
