Feature request: Support contenteditable in addition to input and textarea

[MatthewMWR]

Some sites where I would love to use Alex do not use input or textarea. Instead they use a div or a p with contenteditable="true". Here is a good example of this pattern:

I have no background in js or browser extensions, but if I get time I will try implementing this and submitting back to you. In the meantime please consider it a feature request.
