Sorry for the confusion, my wording was unclear.
As you said, Pulse and Core have identical vibration motor and haptic driver, but the UI for the Core was changed (i.e. strongly simplified) compared to the Pulse.
The ‘old’ UI is far superior in every way, so I rather call it the ‘original’ UI.
Anyway, I expected the Core to be superior (or at least identical in functionality) to the Pulse in every way, so not having those great tweaks anymore, to me, felt like those options were removed… because I desperately needed them.
However, these tweaks technically never existed for the Core, so using the term ‘removing’ was confusing in this context.
Thanks for considering bringing back the original UI (maybe only visible after toggling an ‘Advanced mode’ switch?), although it’s too late for me, unfortunately.
