New Version 0.11 & Pre-sets?

Hi and many thanks for this new release. This is an amazing upgrade using the LittleFS filesystem and giving us a massive increase from 16 to 250 pre-sets.
I have just begun testing on a ESP8266 module. You mention a possible delay with occasional freezing during large memory overwrites.

Question - Is this less prominent on a ESP32 due to it being faster and dual core or is the software not currently able to take advantage of this?
