[Feature Request] v-slider thumb is tiny for mobile use.

Problem to solve

I can't drag the v-slider on mobile. The v-slider thumb is too small.

Proposed solution

Changing the size of the thumb for friendly UX on mobile. Like this thumb https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_rangeslider

The v-slider thumb slider was built to match Material Design 1 spec. The newer version has some style updates that we will be implementing in the future as part of our MD2 update. Because of that, this issue is not required as all components will be updated to match.

I asked him to open this. It's fine visually, but the touch target is so small it's almost impossible to use.

Quickly fixed this by enlarging the slider touch target through a none-destructive CSS addition.
Specifically, I added a :after (new pseudo element) and set it invisible. Now the slider is a joy to use (as the rest of the frame work) as it's easily manipulatable. The fix can be made simply by adding this to your general / default css file.

.v-slider__thumb:after { transition: 0.3s cubic-bezier(0.25, 0.8, 0.5, 1); content: ''; color: inherit; width: 400%; height: 400%; border-radius: 50%; background: transparent; position: absolute; left: -150%; top: -150%; }

Of course vuetify is welcome to add this as well. @johnleider
Also, I would suggest modifying :before to make the touch effect adoptable to different v-slider__thumb sizes.

.v-slider__thumb:before { transition: 0.3s cubic-bezier(0.25, 0.8, 0.5, 1); content: ''; color: inherit; width: 200%; height: 200%; border-radius: 50%; background: currentColor; opacity: 0.3; position: absolute; left: -50%; top: -50%; transform: scale(0.1); pointer-events: none; }
