Allow to customise width

[IgnacioHR]

Current width is "thin", I would like to be able to select the width, or, at least, select between "thin", "medium" and "thick"

Also, I like how this control is able to obtain min and max values from other entities, but the visual representation of the minimum, and maximum could be improved by changing the bar color. like here: gauge
