Hello just started using Volumio the other day which is a great software but the only thing i find a pain is when i use my iPad to control as the buttons along the top row are a bit small ie the Play Button and the others so wondered is it a easy task to maybe enlarge via editing the code ?
maybe this helps: https://volumio.org/forum/improve-volumio-for-iphone-ipad-t2439.html
somebody posted a solution for this but i cant find it right know 
Thats the way i have it setup on my ipad but still find it to small
