Yes, you selected the correct plugin type. Exit the editor and it will ask you whether you wish your changes to be saved. Remember to enable the newly created plugin in your mod manager. Also, you edited the already exiting wetsuit that came with the Far Harbor DLC. The plugin just alters (overrides) the already existing wetsuit.

Correct. You cannot edit a master (.esm) file directly. You'll need to make a new plugin for that. Right-click the marine wetsuit entry and select "Copy as override into". See the attached image. Select the .esp type plugin and give the new .esp a name. You'll be able to apply the effect in the new .esp file you created.

Try to walk beyond the green borders of your settlement. The workshop mode should then auto-close.

Exactly which site rule am I breaking by abandoning a mod? If there is no such rule, then I see no reason to debate this any further.
