we have had this request a number of times, it is in our feature database, but I don't know when it might be implemented.
Do you use the tap and hold feature with the sliders. If you tap and hold on either side of a slider it will start to move slowly so that you have the ability to get to a more exact number.
Also, I find that using a stylus helps with accuracy on sliders.
Thanks for the tip, tap and hold simplifies things a bit.
But it would still be great if you could enter a value also
