I am addicted to making Greasemonkey scripts. I started making scripts to help me in an online game I play, but now I make them for many other sites.
For my clients, I have made Greasemonkey scripts that can:
- scraping data for import into spreadsheets/databases
- adding AJAX to a site that didn’t support it before
- creating mashups (e.g. linking your CRM to another website)
