Default worlds configuration vs portals

[LO1ZB]

I would suggest a similar solution like @STR_Warrior
settings.ini:

Code:

[worlds]
[WorldName]
default=true
nether=Dimension _Nether
end=Dimension _TheEnd
[2ndWorld]
nether=cookies
[3rdWorld]
end=banana

and allow to create custom portals via plugin.
Default value for "default" is "false".
