Finally I found some time to use Foundry in a couple of projects in the last week(s).
(I am this sort of guy who sees something, likes it and then never uses it - and Foundry is cool, I am using Bootstrap with almost all of my web projects (Java/Grails, PHP).
One thing bugs me: the QRCode Icon from Font Awesome doesnt work, it’s not displayed. There’s a typo in the class: it is fa-qr-code but should be fa-qrcode - I have a project, a companion site for a app I have written, that makes heavy use of this icon, so I have to span it all the time, not ideal for something that could be easy fixed.
Is the icon list something global, can I fix it on my own?
