Sorry, it's that I couldn't see it in action yet.
Could anyone post a screenshot to see what the UI looks like? (thx!)

Great! Well done! :)

Well, in some Adobe programs like After Effects when you right click over a
parameter value you see a menu entry "Edit Value...". Selecting this option
opens a dialog letting you redefine the default span of values the user is
allowed to interactively drag this parameter into.
The programmer sets this span to what he believes is the useful range of
values for that parameter, but if the user needs to go past that span, then
he can change that from within this menu (or he could simply enter
numerically a greater or lower value directly, of course).
This is sometimes handy when the useful values are within a very narrow
range (say, 0 to 0.1) or so and then even pressing SHIFT to drag slowly
isn't enough.

Greetings!
