Yes, Andrew, 100% agree !
"Don't throw the baby out with the bathwater", "Schütte das Kind nicht mit dem Bade aus", are the English and German proverbs. And I trust there is a Czech equivalent, Menion :-)
Presets are the only sensible way to control the pain of the massive set of parameters that Locus thankfully has.
I'm thinking of concepts people may be used to from other gadget experiences. Cameras come to my mind first of all.
I am used to this scheme, which is trivial to understand: to play with ANY setting until you are satisfied, then simply assign that to one of the presets available (1 .. 3 in my current camera)
Obviously Locus is not a camera, so a few tweaks do help:
1) allow meaningful names instead of numbers: check, already there, easy to understand for everybody
2) leave/ignore switch for each preset (if the "snapshot" at the moment of Preset definition includes the current value or not is irrlevant (whatever is easier to imnplement), key is that when chosing/activating a Preset later, the particular value is NOT changed: there in principle, again easy to understand for everybody
In summary: where is the problem ?
