Lists

Lists are a feature of Geometry Dash, being introduced in Update 2.2. They are accessed from the creator menu.
Description
Lists are, essentially, user-created gauntlets. The player creating the list can choose what levels to put in there, then can give the list a name, as well as a custom icon that appears next to the name. Certain lists can be picked to be featured, appearing in the Lists section of the menu. Beating every level in a featured list will grant the player a specified number of diamonds, as well as new achievements if they beat enough. Lists can be found on the Search tab by clicking the List icon. This will bring the player to a separate search tab for lists.
