It will be helpful in 15sec games, which I believe will appear here soon!)
This feature, though, should be very well-thought, because it's very difficult to make it comfortable.
For example, you make one premove, and then you want to cancel it and make another. If you just will make another move, as we do now, it will create the second premove, and all the line will be broken. So, there should be some special keys.
2: for the second premove, 3: for the third. Then, what if you would like to cancel your second premove? Maybe, you again press "2", and input another move.
What if you want to cancel all premoves after the first, but leave the first? Maybe, you would press "2" and delete, which will cancel everything after the first premove.
The question is, will it be comfortable to have so much options, and will it be easy to manipulate all these keys during fast 1/2 game?
I personally think, it will be very useful after some training. So, you will need a few days to master this new skill.
I think, it worth it's implementing.
Also, would be nice, to have it implemented together with ¼+0 time control.
