Krypto Skrypt mod menu. What do you think?

yuh
The mod was technically supposed to be only for me and my friends, it was a simple GUI about the same size with no tabs and what not, but I decided that I wanted to publish this and make the mod a little better... so yeah. The sandbox tab is probably what's going to make this mod shine, it's a tab full of server-side features such as changing your gravity, health, speed, jump height etc, and no this will not work on multiplayer servers, but don't worry you can use the server side features by making either a LAN or peer-to-peer server, or just by playing by yourself?
So anyway this is here is Krypto Skrypt, my first Lua script ever published, let me know what you think and if you have any suggestions.

Oh, and I can't take any more pictures because it's taking up to much of my storage space, about 20GB a picture.
