Indeed. But if you can always return to the original value
without having to type it that makes things easier.
indeed, this is a separate issue: essentially ensuring that there is a
precise mapping of pixels to integral values of desired units (and
back), rather than (as typically happens) pixels to some fractional
value of desired units. e.g. I don't want to be able to tune to
+2.8291 semitones, only to +1, +2, +3 and so on.
Maybe you want fractions, but the integer values should be
available exactly.
In many cases it doesn't matter very much. But even for e.g. a
gain fader I'd expect it top have a position that is *exactly*
0dB, and more in general I'd expect any tick marks to be exact,
at least in the -20dB..max range.

If you don't want to change the current value,
don't touch the slider.
Very easily done accidentally in a dense layout. If you want finer control of your parameters, there
are different approaches.
This is not necessarily about finer control, but about having 'preferred'
parameter values (e.g. semitones for an oscillator frequency). This should
always be possible without having to type numbers.
