Yes, I agree and thought and posted about it too often here. And made the feature request to be able to disable autosave or ability to tag reload pattern on change or write protect a pattern with kit.
After you jump to another pattern spontaneus or by accident after playing around you have to be sure the other patterns in project are in a saved state you like so that you can reload the project.
For not spontaneus or accidental pattern jumps, if you want to do a save pattern as ( including kit sounds changes with encoders):
-Tag kit reload on change,
Copy pattern, reload pattern, go to new pattern, paste pattern, save new kit with new name , save pattern.
On digitone there is the nice reload from project command, ( but kits are missing more or less),
On ot pattern reload is not possible.
Both situations are clear.
But on a4 the pattern reload text in the manual gives me strong headache also after reading 80 times.
I miss disable autosave on all machines.
