Thanks. Also SERVO10_xxx appears before SERVO2_xxx

The issue is that parameters are sorted alphabetically and numbers do not maintain consistent width, we would have to rename all parameters where there are 10 or more instances to always use two digits numbers. IMHO it would be nicer if we could show instantiated parameters as for example SERVONN_*so we don't have to scroll or search through 32 instances of servo parameters.

We discussed in dev call yesterday and the recommended approach is to use a regex to discover numerics. We need to sort by the numerically instead of lexographically, which should solve the less-than-10 more-than-10 issue that the code currently has.

Please consider grouping them, this will make searching through parameters so much faster.

I'll see what I can do!
