First of all, thank you very much for this great plugin. I think I will use it instead of Vimwiki.
When using the following minimal setup:
let g:wiki_mappings_use_default = 'none'
Plug 'lervag/wiki.vim'
I expected no mappings would be set.
However, mappings like <leader>wr still seem to work.
Running :verbose map <leader>w shows a lot of mappings.
