Call this game 'recycle' as that's where all the time goes. It would be better to have icons for delete, recycle and maybe split. Then we could just drag and drop to the icons instead of click item, choose button click pop up and then continue. Another idea would be to give us some stats on our current build of an item and then show the stats for the next upgrade so we know what we get for our supplies we use.
