Notes:
- [SiegeWar's config includes "map_hiding"](https://github.com/TownyAdvanced/SiegeWar/wiki/Siege-War-FAQ) which will override Dynmap configs for hiding users in wilderness / underground / besieged-towns. This can feel like users 'randomly' not appearing on the map.
+### [WorldBorder](https://dev.bukkit.org/projects/worldborder)
+
+Common companion addon to Dynmap to provide commands to pregenerate and trim worlds. Dynmap only displays generated chunks so has obvious benefits.
+
+Note:
+ - WorldBorder will only generate chunks when commanded to.
+ - Dynmap will only display borders automatically. You need to configure Dynmap visibility region to be same as WB borders.
+ - You may need to use dynmap purgemap
if you have already generated terrain beyond the borders.
+
+### SkinsRestorer
+
+SkinsRestorer is a plugin that restores skins for offline mode servers & networks that gives the players ability to change their skins by typing a single command.
+
+Code is provided directly from the developers. Dynmap cannot support this directly - please refer back to the developers.

+At this time, hybrid platforms are not supported. See this [issue marked 'Will Not Fix'](https://github.com/webbukkit/dynmap/issues/3482#issuecomment-986661674) for details (Dec-2021).
