This is all good news and it's great to actually have some of that from the Lab these days.
However every silver lining has a cloud so to speak, and this stories' cloud is that once again, some improvements are only being rolled out to viewer 2. There is only 1 tiny little problem with viewer 2:
WE DON'T LIKE IT!
Time and time again, all we see in these blogs is that long term SL users hate, hate, hate viewer 2, yet still you push, push, push it down our throats, by only including important code releases into this clunky, poorly designed and unintuitive viewer. (http_textures, mesh etc,etc.)
Yes I understand all about the difficulties of having 2 code bases to maintain, cost benefits, and blah blah blah; and I also appreciate that you have launched snowstorm to try sort it out - However, this was your mistake. You went ahead with the awful thing despite repeated and numerous complaints from virtually every builder, scripter and power user out there. Now with snowstorm, you've pretty much admitted how bad it was, yet still we only see improvements going into viewer 2. You OWE it to us power users to put these important features into the viewer that we all use.
