FixxeR helped me with Linked List, so now I use them for handling my custom structs for Graphics and stuff.

It is unpracticle using Linked Lists instead of an array. Never mind, I will use a counter instead It not that important anyway

BTW, I had to define my own Graphic Linked List for PANELs because I noticed there was no 'ent_next' for panels. Perhaps you can implement it...?
