About Acronym Expander

Research papers and articles often utilise non-standard acronyms (NSAs) that are introduced early in a text and then used throughout, and these are surprisingly easy to forget. This extension automatically identifies these acronyms on websites and adds tooltips containing their expansion to each one - allowing you to hover over them to see their full meaning. *** New in v2.0 *** - MAJOR UI overhaul, with multiple bugfixes behind the scenes. - Added light/dark themes - Forwards acronyms now supported (e.g. 'NSAs (Non-standard acronyms) will now be identified) - Improved ability to identify acronyms in sites with 'weird' HTML *** New in v1.9 *** - Added ability to manage the stored acronym data for sites, including automatically deleting the data 'x' days after the site was last visited ! - Added regex support to create lists of sites to NEVER tooltip (e.g. github, youtube, etc) *** Key features *** - Automatic Acronym/Expansion Detection - Customisable Acronyms: Delete, edit, or even add new acronyms - Stored Site Acronyms: Acronyms are specifically saved to each site, so when revisiting an old paper you can still see all your automatically/manually saved acronyms ! - Create Key Acronyms: Key Acronyms are implemented across ALL sites, so you can create a central bank of acronyms/expansions (for example a list of genes and their functions), and have these automatically applied to every paper you visit ! - Toggle Acronym Visibility: This will turn off all non-key acronyms, useful for when you're reading a familiar paper - Import/Export Key Acronyms: Key Acronyms can be easily imported/exported to enable quick sharing and personal storage ! - Hidden Acronyms: Acronym-Expansion pairs that won't be tooltipped on any site (useful if theres a common acronym you come across a LOT) - Control tooltip sizing
