Drop-away side panels were implemented; and for spells and special effects, 3D support was added.[75] Pathfinding had been improved in Tales of the Sword Coast (the Baldur's Gate expansion), and was improved further in Shadows of Amn through a feature called "bumping", which allowed a character to move another one out of the way if the path was blocked. Also, to aid pathfinding even more, paths in dungeons were widened, so that characters would get stuck less often. The interface was also refined a bit.[76]
