For when re-sorting lots of items under different parent, I find that grids are often not very responsive and the items feel slow to move. When I try to use key repeat, say when I want to move an item up by ten spots, the keyboard buffer is quickly filled up with stored Alt-Up commands but IQ takes a long time to process each command so it often gets stuck in some kind of loop and the item moves upward several times more than intended, with IQ often becoming unresponsive for several seconds.

Is there perhaps something you could tweak to make it work a little faster 'out of the box'? Alternatively, maybe some new commands ('move item without updating anything fancy in the grid') would be possible, or a special mode for quickly re-arranging things without any advanced things being updated in the grid?

Many thanks!
