This is a tiny little client side Chrome extension that integrates commands you can use on any Stackexchange Chat.
Right now, these are the commands implemented:
##notfunny##cry##scream##surprise##blankface##sad##todaypaella##notpaella##dance##workface##ugh##sleep##frustration##bored##shruggie##hiya##surprise_old
In case that you want to add new commands/pictures you just need to edit the background.js file and add the new line in the list of emotions.
...
new Emotion('surprise_old', "https://i.imgur.com/V5Bgq0u.jpg"),
new Emotion('codeWord', "imageUrl")
];
And to use it just call ##codeWord
Right now the extension is not on the Chrome Web Store so, to be able to use it, it's necessary to download the code, extract it on a folder and then, add the extension as an Unpacked Extension.
