@fgregg my first instinct is to do a vertical stack, how does this look? i can hide on mobile if you think that's the right thing to do.

I think the vertical is okay, but the differential weight of "Download Data" doesn't seem right for this viewport. It looks like it's the most important thing, and what you probably want to do.

Can you try reducing the weight for smaller viewports?

@fgregg something like this? we can style this however we need, i can go a lighter gray or not even fill in the button. i could even do no button.

Looks great!
