I suggest that you add a typing-notation which means, 'search this'. Perhaps, "[supreme court smith maryland]". Then, when the close-bracket triggers the search, one of the 'pin' options on the results will offer single-click replacement of the "[*]" with a persistent association to that sticky sidebar-result.
If different users can plug in different search-backends, many hypertext-writing domains could be accelerated, including Wikipedia, legal, blogging, etc. Maybe even you could have an image-suggesting mode for finding quick (and perhaps liberally-licensed) supporting images?
(I'd add Pinboard/archiving-support as well... so everything pinned gets snapshot against link rot.)
Your links/refs column is also a bit reminiscent of https://gingkoapp.com/ – your two projects can probably draw inspiration from each other.
