Each land system is different and supports a different array of features. Flags attempts to work with as many of these unique features as possible while still conforming to the general standard API. Below is a list of supported area plugins, the minimum versions required to work with the current version of Flags, and a list of capable features of each plugin. The feature list only contains features that Flags interacts with, each system has it's own unique design and feature set. Do you use a area plugin Flags doesn't support? You can request support for new systems by making a ticket or posting on the forums.
