If they implemented that idea then each LED mode would be synchronised, I feel like that would take away what I love so much about this model.
True enough, though if you insist on individual modes memories (which I agree are of great convenience) that probably can be done too - for instance, the intensity dial could have a MEM position. That would probably require something like MEM button as well: pressing it in each of the modes would memorise the intensity (unless there is a more elegant way to achieve it).
