[Bf-committers] Why must sync selection be disabled to select UV islands?

[Paweł Łyczkowski]

I also always missed this. When selecting in vertex select mode, I would 
expect for vertices in other islands to be selected as well. I would use 
it in face select mode though.

I usually went around this by identifying where on the model is the 
island I wanted selected, and then used select linked with limit with 
seams turned on in the 3d View - but that's a roundabout way of doing this.
