UI Iteration Feedback

Feedback from QA UI experiments (https://qa.fatcat.wiki):

- shorter/fewer blurbs on front page: "what is fatcat" and "institution" paragraphs in a single bar; beta note just a single line
- file search for URLs (of files or webcaptures)
- release search: `release_stage` not status
- generic search view which looks for identifiers and some URL patterns, then redirects to lookups or release search as appropriate
- joi's "citing blogs" release is dataset; should be weblog-post or whatever
- all lookups of all entity types could be a single page, but fine as-is
- entity pages, should show counts for tabs (before clicking)
- release entity page: abstracts and files on overview; refs and metadata as pages
- entity pages: fixed sidebar size (not window-resize-specific)
- entity pages: need to emphasize edit/history tabs
- examples on front page could be full/real examples (eg, citation text as a link) instead of slug-like "Paper", "Journal". Would probably require a redesign of box
- fixed minimum width on desktop (instead of continuous resizing

Thoughts:
- files/filesets/webcaptures could be single elasticsearch index

Start with the QA UI experiments at https://qa.fatcat.wiki and review the listed front-page, entity-page, lookup, and search feedback. The issue contains multiple independent redesign and search requests, including a possible shared Elasticsearch index; a contributor would need a narrower scope and acceptance criteria before implementation can begin.
