Option for Kupfer to not automatically clear query input after 2 sec. of inactivity?

Hi everyone,

I'm still using and enjoying Kupfer daily. The biggest annoyance that I am facing recently is the way that Kupfer clears the query entry after 2 seconds of inactivity. I sometimes have to think a little bit about what I am searching for, especially as the results list is refined and updated, so 2 seconds isn't enough. And for other features, such as the calculator, the automatic clearing of a partial query makes no sense, since I often have to delay considerably while looking for values that I want to calculate. At the same time, the queries should not persist after Kupfer gets hidden, i.e. the query SHOULD be cleared for the next search the next time Kupfer is invoked after being hidden. Is there any way to do this?

Thanks a lot!
