Filter not available on mobile

Thanks for this fantastic app. I can see many uses for it and gave already adapted it using some open data from my local council.

I noticed that on the mobile version the filter button doesn't show up. I guess most users will be in the desktop so it's not a major issue but thought I'd let you know.

Cheers
