Probably yes. There are at least two kinds of useful LifeHistory "clear" operations, though:
1) Clear just the blue state-2 envelope cells, leave marked cells and state-6 cells in place.
2) Convert LifeHistory to plain Life, changing all odd-state cells to ON cells and all even-state cells to OFF cells.
There might be a third, I suppose:
3) Remove the markings on marked cells, so state 4 goes to state 2 and state 3 and 5 go to state 1. State 6 would probably be left alone in this case, since it's not technically a marked cell.
3b) I wouldn't mind if state-6 cells just disappeared when cells got unmarked, though... or "state 6 only" could be a fourth type of clear operation.
Maybe a hotkey could be assigned to one of these, and Shift+hotkey or Ctrl+hotkey or whatever to the other(s)?
