I used griffpatch's tutorial on grid lists and how they are useful. This now does not work and will be removed soon. Sorry about the glitches but when adding a big feature and Scratch auto-saving, the feature seemed to mess up and I can not get back to my previous save. The feature was not correctly coded and the Scratch was saved. After I tried to remove it and tested it but everything messed up and now is this monster. Sorry about this!
