I wish glass had a colour border when trying to align another glass panel with it, it could disappear when aligned correctly. I've made a decorative window near the front door, it would look great if I could see the edge of the pane better when placing them. I use setp 1 command to get it close, but not close enough. Or I wish the bubble and lined glass could be made bigger/smaller with out the texture getting stretched as well.
Another use for posters. I really like this, its exactly how I wanted the window to be. It even has a transparent feel to it and looks great on the outside too.
