Text inside thumb

[suhitak1]

Hello

I have following queries:

1. Is there any way by which I can set text inside the thumb as well to display progress?
2. I want to highlight the progress with another color, e.g. if there are 5 ticks and I am on 4th tick. I want the progress color to be changed till 4th tick (index 3, from offset 0). Currently entire progress is using transparent theme; instead it should use same color as thumb to display the progress made.
3. I want to change the thumb position. It should float above the slider; like balloon.
