Q Light Controller+

I'd like to know if it's implemented or planned the live control of media size and position, I couldn't find a way.
maybe will it be possible with the VC xy pad?

I think we already discussed this. However, I can't find the relevant topic.
Please define how you would like it to be so that we can discuss the details.

Please do not propose a pixel based solution, cause it won't work on different monitor resolutions.
I imagine this to be percentage based.
Something like:
- position control (X / Y): from -100% to +100%
- size control (W / H): from 0% to 1000%

yes we've spoken briefly another time and the relative proportion to the picture size it is good choice, other software use this approach too.
In this case I'd suggest pivot point in the center, I've noticed that X-rot and Y-rot use the side of the image as pivot point and it's convenient, while Z-rot uses the center.

SCALE
I propose separate X and Y
0% it's good because it allows to scale out/in from a point
1000% seems to be enough, it correspond to double the size 3 times and an half, otherwise we could consider 4 times that correspond to 1600%.

POSITION
again separate X and Y
with -100% > 100% do you refer to the screen?
because considering the scale factor it would be good to be able to pan the image from outside to inside the screen and vice versa.
