Thanks all for your messages, I’ve responded in one post to keep things more concise:
@fuzzy.beach, in the “Search in View” prompt, previously we were searching all your cards in the view rather than just those that were being filtered. So now you can narrow your searchable cards down even further using the filter menu and then use “Search in View” to search just those cards, we think this is a more flexible approach than having variables directly within the search itself.
@Fizzster21, the unexpected Tab Behaviour is also a high priority bug fix and will be fixed in 3.1.2. Generally if you notice that a bug that has been introduced because of an update, we will aim to fix those in the next one or two releases.
@solsen thanks for the kind words 
More updates and fixes to come. If you notice anything else let us know
