It might sound like a toy for people who love endless customisation, but there are some great scripts around that can benefit researchers. A few examples:
- Pierre’s pubmed2connotea – adds icons to a PubMed results page to bookmark references at Connotea, CiteUlike or del.icio.us
- Pedro’s postgenomic script – marks articles at Nature journal pages that are discussed at Postgenomic
- Connotea tools – a bunch of scripts to move bookmarks between Connotea and del.icio.us
Lots more scripts can be found at userscripts.org. Another of my favourites, not strictly science-related is two column Google, which displays Google search results in – can you guess? Much more convenient to view if you have 1280×1024 or wider.
