in the graphics editor, the line tool only lets you snap two lines at one point. we can make stuff like triangles using this. but, what if i need <i> three </i> points to be connected? scratch won't snap it, and you will end up with some out-of-place bit that ruins whatever you're trying to make. so, y suggestion is, to be able to snap an infinite (or maybe limited with a high number) amount of lines to a point. with just 3 lines, we can already draw cubes and cuboids, so having more could also be beneficial i guess. if you don't understand then uh: lines don't snap if you put too many, so if too many, MAKE IT SNAP
