That's not a bug, that's how that specific compression type works. Try using other compression algorithms in the import settings of the texture

I'm afraid not!

Well, you can do the same thing with 3 less nodes, which is clean enough to me :)

As for having it in the UV node itself - you don't always use those values, I think it's nice to not have them there, and do it manually as shown above

Not at the moment - currently a bit too busy with another project I'm afraid

Try enabling the scroll wheel for the quickpick menu. If that doesn't work, you may be able to use the sidebar for placing nodes. If that doesn't work, try a full reinstall: http://acegikmo.com/shaderforge/faq/?Q=erroronnewversion#erroronnewversion

Sounds really odd. Any errors in the console?

Please ask this in the forums (http://neatcorporation.com/forums/viewforum.php?f=4) instead of here

There's no way to use multiple UVs, there's only one UV coordinate when sampling a texture. Please ask this in the forums (http://neatcorporation.com/forums/viewforum.php?f=4), this place is for bug reports and feature requests, not "how do I" questions

You'll need to figure out based on what parameters you want to blend them. Anyhow, this is a question for the forums!

Negate or reverse the UVs you send into the texture samplers
