Implemented a new "super knife". Activate with k. Holding CTRL will allow extended cutting ala old lines mode. Confirm with enter and escape. You cannot cancel, btw, you can only confirm (and undo later if you want). Hopefully I'll support undo within the tool soon. * Supports cutting edges, into faces, etc. You can pretty much do whatever you want. Will snap to vertices too. * Note that if you cut into a face, it must be valid topologically when you press enter to confirm. * It's pretty and graphical :) * You can only cut visible geometry. * UVs/vcols are a little buggy still Now, thou shalt all cease and desist all lack of motivation for testing! No longer shall users put off testing until "it's cooler"! :P
