Feature request: side-by-side preview?

[larsw]

Hi,

Would it be possible to add a side-by-side preview option?

This would be a nice addition, but in the current state of the app it would require quite some effort.
I will definitely have this in mind if someday I decide to rewrite the app as a SPA.

In the meantime I'll gladly accept PR if anyone is willing to give it a try.

I also find this to be a feature that i want to use. I will take a look hopefully come up with a PR in the near future.
