When I select category: "dir&files" and "apps", type my phrase and search - I have correct results in both groups, then clear input and type sth else again, where there are no "apps" results, then apps filter disappear.

But when I clear input and type first phrase, only "dir&files" category is active, I have to manually select "apps" filter to find my app.

First problem: how to make sticky filters?
I want to select 2 categorys once, hide filter panel and get the same results every time.

Second problem: how to set the category results order sticky , I mean "dir&files" is always first, "apps" is always second, if no dir/file result, do not hide category panel, simply do not show results
