You're welcome!

After struggling with label legibility vs making it stand out where the 
value bar ends, I figured the bar only needs very little height to 
remain readable, if the contrast is strong. The behind-the-label part 
only has to show where you can drag on, with the toned down bar making 
sure everything appears as a unit.

The first variant with separate numerical entry area may suffer in the 
case where after dragging the bar to within the entry part, you might 
release and try a drag back to the left. Implementing a duration and/or 
drag threshold could avoid accidental numerical entry activation, but 
could only hurt on the rest of the widget. It might be better to not 
have the bar-range extend to within the entry area. This variant here 
happened because of stubbornness in wanting both maximum length for 
fine-grained value indication and numerical entry with fewest clicks!

BTW, the thingies to the left of the sliders are meant as automation 
activators/indicators. The very first one is in the no-automation state. 
Clicking it should show/create an automation track. Once there is 
automation, it appears as in the second row.

Drop me a line, if you would like to have the SVG file.
