Improving the perspective control grid

Question

The perspective control for photos is for me the best thing that has happened to LR. I can ( just ) about cope with the speed reduction, but the control for verticals, for rotation and for horizontals is superb.
At the moment it appears that the centre of the photograph is the point where the rotation and the vertical and horizontal transforms reference from.
As soon as you select the Vertical / horizontal / rotate / distort, the grid appears that aids you in setting the verticals etc.
There is no way of seeing the central point, where these transformations occur, you ony have the grid, so I am thinking that when you press the modifier keysthe control / shift  / alt keys, a cross appears over the central point of the grid. This would give you the location of the central point. Plain and simple.
As soon as you release the modifier keys, this disappears, so you can just see the grid.
This would speed up rotation tremendously, as this is your reference  point, at the moment, I juggle the rotation and vertical to get where I  want to be.
Alternatively, like the Crop has various layouts, so pressing "O" could  scan through these same grids, but we will need a central point because  at the moment the crop does not have a grid to mark the centre of the  image.
LR 4 may enable you to pick your reference point to do the transformations from, then, apply the same principal to that point with the overlaid rotation marking cross.
Any thoughts?

function(){return A.apply(null,[this].concat($A(arguments)))}

Would be an interesting combination, however, none of lightrooms controls use any controls like the PS transform controls, so I think its unlikely they will do that.
Good luck, but try the arrows and expecially zoomed in and see if learning a new trick works for you
Using the arrows is old hat.  I agree this helps for small adjustments.  I use it all the time.  I also like your idea of establishing a reference point.
Regarding your statement that no LR controls are like the PS transform - I disagree.  The LR crop tool is similar (size, aspect and rotation).  All I am suggesting is that the vertical and horizontal transforms be added to the LR crop tool, similar to how the PS crop tool (not the PS transform tool) works.  There is no reason why zooming into the image could not be supported.
Consider this example.  You are copying a document that is rectangular and located on a desk.  You cannot place your camera directly over the document, so you take it at an angle.  Then you want to correct in post processing.  Using the PS crop tool, all you have to do is drag the four corners of the crop rectangle to the four corners of the document.  Done.  Try that in the current LR implementation.  It can be done, but takes a ton of fiddling.
So, I still want both ways of correcting perspective, and I do not think this is against the "LR way of doing things".  Adobe modified the crop tool, based on beta tester feedback, and they may well again.  At least I know they will look at this carefully and come up with improvements based on their track record.
