I've uploaded a pic showing how much better (and accurate!) they now are... :)
Also added a few fixes and tweaks... :)
Will be uploaded later on today when I've had a good sleep (3am UK-Time now... Zzzz....) and a chance to thoroughly check the build!...
When in the editor, these will also dynamically change on-screen, to show the current edited level state, then save out with your level... :)
