Zooming in the UV Editor should center on the mouse cursor or view center.

The whole EV Editor is broken :(

1) Zooming and panning is seriously annoying. Many times panning stops working (I think it depends on the zoom value or something). Sometimes panning works only in one axis for no obvious reason.

2) The white grid is blinking constantly.

3) I have many vertices out of the screen and I can't see them because the panning function seems to have some constraints and my vertices are somewhere beyond these constraints.

4) Mouse drag selection seems to work only when you are dragging from top left corner to the bottom right corner.

5) Pressing the undo keys CMD + Z in that windows many times breaks the whole GameDraw (I have to restart Unity to make it work again).

6) Would be great if I could select the faces in the 3D view and then manipulate them in the UV editor.

I am disappointed at the moment. I was so happy that I will finally be able to make a level inside the Unity, but I need the UV edit to work to make it happen.

Maybe you could make some quick patch to fix the pan function so I could at least pan to the vertices out of the screen? The other issues are annoying but this one makes it really impossible to work with the editor.

I think I will probably have to use GameDraw to manipulate geometry and the other tool ProBuilder to manipulate UVs. Then GameDraw again to fix the lightmapping UVs :D We will see if it will work.

Ehh it's not possible to use ProBuilder with GameDraw, they don't cooperate too good. My only hope is that you will fix the UV Editor soon :/

I have find some way to work around this problem. I am scaling everything down in the UV Editor, selecting everything, scaling it up again, moving it to the visible part of the view, and now I can work with all vertices :)
