Suggestion: don't lose search strings. Example: in the search box type "Panda" -- a modal window pops up with 6 matches. Which one do I want? I click one. It fills the window. Nope, that is not the one. So I click the Back button-- and the search box is empty. I have to type "Panda" again. That is annoying.
Probably you should just repaint the main window, with the search string intact but showing only the matching selection of titles. Then one could alt-click to open a title in a separate window or tab, and not lose the search.
Another suggestion related to search: please implement a URL route to initiate a search. I would like to define a search template to easily start a search from LaunchBar. Something like https://whereto.stream/search?q=*
