The Value Control is great because it directly shows a numerical value (not like the sliders that hide the actual value).
However I often find it too limited in internal configuration options.
The first and most important missing feature is an "Integers only" option. When checked, user can only enter integers (i.e. 0,1,2,3.. and not 0.1234).
The second missing option is range control. The remapper gives you some *remapping* options, which is not the same. A range specification would mean that if you specify min and max values = -2, 2, *any* value outside this range will be clamped to the defined min/max range.. so -4 is clamped to -2 and 567 is clamped to 2.
I know it is possible to "post process" the value input internally in the filter, but that is not very user friendly or efficient (since the post processing takes place per sample and not prior to rendering)
