Transpanner 2

Thank you! After a few tests I can say: this plugin sounds great! doesn't even use that much CPU. Cool.

The only thing I feel a bit cumbersome is the fact that dragging towards the center sends the sound to the distance. It is quite disorienting, basically the opposite of what I'd expect. Because of this, the movements you have to perform to create a realistic trajectory are quite difficult or unnatural (e.g. if you want to go from near front to near back you have to pass through the "center/distance" which makes no sense, or if you want to go from far right to front right then move to the left then far left, you have to draw a shape of "a drop" upsidedown which feels a bit weird (rather than a simple U)). If the center meant "near" the motions would be much easier and intuitive. my2c.
Besides this UX issue, I find it great.

PS: an extra knob to tweak amount of reverb (size of the room) would be the cherry on top.
