I want to collect some thoughts on how we can improve the References component now that #12 is in. We can migrate some of these to separate issues as we work on them.

• What should happen when we click on a reference? The two most likely actions would be to open the PDF for reading or to expand the reference to display more metadata about it. Maybe we do both, with icons? (issue Improve click behaviour on references #174)
• Upload target: as the library grows, the upload target will move down the screen. Should we consider moving to a tabbed layout with "upload" as a tab next to "library"? Or some other solution? Also, I'd like to make the whole component a target for files that are dragged over it. (issue Improve upload target for references #173)
• We should ultimately use a table for references that can display more metadata such as journal and publication year and allow for sorting and filtering. (issue References table view and reference detail view #159)
• The ingestion pipeline should display more complete information about its status while running, and we need to display information about how references have been processed after the ingest pipeline has finished, e.g. the PDF is available in the local project directory, metadata was parsed successfully from GROBID, content has been extracted and made available for AI interactions, etc. (issue Ability to display Reference ingestion status #113) (issue UI to display ingestion status #194)
• We should allow the component to be configured and remove the permanent display of the project storage directory. Configure project storage location #286
• References need a unique key, to be used in the Markdown representation of the citation. (added by Generate reference citation key for ingested references #112)
• We could automatically generate a key on upload, and then allow the users to edit the key if they want. A common choice for a key is the first author's last name plus the publication year, e.g. hammerbacher1999. If there's a key collision just append a, b, c, etc. If we don't have metadata just use untitled plus 1, 2, 3, etc. (added by Generate reference citation key for ingested references #112)
• Allow for multiple references to be included in a single citation. In the Markdown representation the keys will be separated by a semicolon. Allow for multiple references to be included in a single citation #287

Also as a reminder, 3 longer-term issues we won't work on now:

• Allow users to search and select references #138
• Disambiguate, normalize, and link references against external databases #140
• Retrieve full text for references #141
