Search panel for three fields

Product suggestions:

(1) I would like to see a search function (panel) that can search for a term simultaneously in the reference pane (specifically the “research notes”), in the linked pdf text, and in the sticky notes.

(2) And having the reference pane or the research notes pane and the pdf pane open together instead of having to toggle back and forth between research notes and pdf text.

(3) to be able to collect highlighted text within a document  together into a separate pane and to search for terms within that pane as well
