This mod rewrites the generation of end cities to make them much larger and with many more branching paths.
The config file can be used to modify the:
Max number of ships per city
Max height of each middle tower
Length of the bridges
the best values i have found is 8 for the middle towers, and long for the length of the bridges.
Though there will be some cities that are cut off at height limit.
If you are using this mod with BetterEnd then you should lower the settings as the bases will be higher up.
this will work with better end city datapacks.
