I have an idea for a redstone item that would make some redstone circuits a lot easier to make, and that would be a 'flip-flop' block.
How to use it (if it existed):
1) Place the block on the ground. It looks like a repeater with no torches, and it's textured to reflect the 'one-way' circuit similar to a redstone repeater except there is also a 'latch' input on one side.
2) Put a redstone wire on both ends of the 'flip-flop' block. Power it up, and it does not pass power from the input side to the output side of the block.
3) Now put a redstone wire on the 'latch' side of the flip-flop block. Power up this 'latch' wire, and now the flip-flop block allows power to pass from the input side to the output side. While the 'latch' side of the flip-flop block is powered, the flip-flop block behaves exactly like a redstone repeater.
4) Take power off the 'latch' side of the flip-flop block, and the output of the flip-flop block stays at the same state that it was in when the power was taken off the latch wire. In other words, the output is 'latched' on or off and will not change regardless of the input side of the flip-flop block.
I tried modding this block into Minecraft and it was pretty easy to get the logic working (if 'latch' is 'on' then pass input to output; if 'latch' switches 'off' then set output to input's state, if 'latch' is 'off' then leave output powered or unpowered based on how it was when the latch was switched off). I don't think it would be a difficult block to permanently implement into a future update of Minecraft, and it would make more complex redstone circuits a lot easier to create.
Uhh
What you're describing seems to be almost identical to one of the more recent updates.
Repeaters, when powered from the side by another repeater, would hold its output signal until the side input was deactivated.
So, either you're trolling or you haven't updated MC in a while.

76q309 is right. From the wiki:
Latch
You can create a latch by combining two Redstone Repeaters: The first provides input and output, while a second, pointing into the left or right side of the first, provides the latch functionality. When the second repeater is powered, the first is "latched", and will remain on or off even if its input changes. (Visually, the latched repeater's delay switch is replaced by a crossbar.) When the second repeater is turned off, the first one will go back to repeating its input faithfully. Note that this is not simply a matter of powering the first repeater from the side, as redstone dust, levers, etc., will not latch a repeater.
This provides the equivalent of a Gated D Latch. Two such latches can also be combined to produce a "flip-flop", aka "toggle", circuit.

No I will not +1 you unless you say something worth +1ing. Respect is earned, not given.
Yep, I've been living under a rock... I tried that and it works pretty slick! I haven't gone to the minecraft wiki for a while since I kept getting adware/spyware when browsing that site, so I did not know that you could pair up repeaters to create a flipflop. Maybe I'll have to juice up my antivirus and try browsing that site again.

Thanks for the info!
I've actually heard word that the Redstone Update will add something like this. So, think that your idea will be in game.
