Encouraging to see work on this. Appreciate the effort you are undertaking.
There's a lot of things about the architecture of FFCRM that make it hard to skin better (not using unobtrusive javascript for example). That said, there is a real end-user need to skin and get this working on mobile. I'd certainly use it!
Personally, I'm unable to support with work effort right now, though I'd be open to merging pull-requests when things are ready.
I will also be taking a break until end of June so will be unresponsive on email during that time.
I guess my vibe is this: highly supportive of your UI efforts, low expectation to be able to assist myself.
Regards and thanks for reaching out,
Steve
