You can now use /tl and /thirdlife.
/thirdlife addlife and /thirdlife reset can now be used in the console.

You can now use PlaceholderAPI with thirdlife so see the lifes of a player. The placeholder is: %thirdlife_lifes%.

Now 3rdLife is also available on 1.17 and 1.17.1

You can now enable/disable the Nether and End dimesion in the config file. If disabled players can no longer enter the selected portal to the selected dimension. They can however exit these dimensions back to the overworld.

In this new version I've just fixed a bug where you weren't taken back into survival mode after a life reset.
