Slider-input usability changes

Hello!
I have two proposals for slider-input-value field:

**Make minimum slider-input width wider by 15% and adaptive to digits count**
Now width of range sliders is 50 px
Setting it to 60-70 px will improve usability of slider inputs in most cases. For another cases it should individual for every slider-input and have adaptive width according to count of digits in parameter

**Make slider-input buttons adaptive to number, that would be changed**
Here grid size set to 0.1 km
After clicking up button, ranges become 1.1 km
Proposal is to make order of difference between initial and final value comparable to initial value's count of visible digits after decimal point. For example if initial value set to 1 without visible decimal point, then clicking up and down buttons will change it by 1. If value set to 1.0 or 1.1, it would be changed by 0.1 and etc.
