It only works in "plain text" messages. Right? Great idea still! I have two suggestions, bc I believe it can be an incredibly useful script: 1st, make it work in html emails. 2nd I write emails in English, Spanish, French & Catalan, so I would love to add more trigger words like "adjunt" for "adjunto" or "adjuntado" in Catalan or Spanish. How can I do that? Maybe you could add some commented lines on the script with instructions on how to port it. Still, great idea!

Excellent idea! I am running it and I love it. Building on what Randy suggested, you might get some inspiration from the Gmail: Random Signature script http://userscripts.org/scripts/show/1704 , where color setup is achieved at the settings menu.

Still, a lovely idea and implementation!

Amazing idea!! I have already installed it, but I would love to change a thing: I write emails in English, Spanish, French & Catalan, so I would love to add more trigger words like "adjunt" for "adjunto" or "adjuntado" in Catalan or Spanish.

How can I do that? Maybe you could add some commented lines on the script with instructions on how to port it.

Still, great idea!
