Simple solution to extend this switching circuit?

Hi,


What I really want is for it to essentially work like a T-flip-flop. One pulse to turn on, another to turn off (the pulse ultimately coming from an other momentary switch). Now I suppose I could just replace the existing momentary switch with a mosfet or some such, but I was hoping another op amp in the equation could do the trick (since I'm using LM324 quads anyway). Not sure how that would be done though.

Please help.

Thanks!



I didn't find the right solution from the Internet.
