Expanded identifier support for ReadCube button
The ReadCube browser button now supports PMID and PMCID identifiers in addition to existing identifiers. This allows users to add articles to their library from a wider range of biomedical sources where DOI information may not be available.
Improved browser extension compatibility across sources
The browser extension has been enhanced to work more consistently across additional platforms, including SciFinder and Psicothema. Styling improvements for Google Scholar in Chrome ensure a more consistent and reliable experience when saving articles.
More efficient PDF download handling
The PDF download process has been improved to better support a wider range of publisher sites. This reduces failed downloads and improves reliability when retrieving full text.
Enhanced tagging during article addition
Tagging support has been added to the article add popup. This allows users to organize content at the point of ingestion, reducing the need for follow-up library management.
Improved usability of tag management menu
The tag menu layout has been refined to prevent interface elements from overlapping. This improves clarity and reduces friction when managing tags.
Consistent browser extension interface
The browser extension interface has been aligned across supported browsers to provide a more consistent and predictable user experience.
