Really nice to be able to search the tabs for those relating to a particular keyword. What is unhelpful usability is that the second you click on one of the tabs, the search results are lost. So if you want to navigate to another tab on the same subject, one has to repeat the search. This is a time waster. In fact, rather irritating. I thought a previous version retained the search results, so one can look through all the tabs pertaining to the particular keyword(s). Please reinstate that behaviour.
