nvim-mapper provides a way to find and remember key mappings, but it requires re-writing your mappings in its special format. The special format provides no benefits except for informing the plugin about the available maps. On the other hand, nest.nvim provides a nice way of formatting mappings in ways that group similar keybindings together, a clear benefit that makes sense to adopt. An integration with nvim-mapper would make it much easier to get the benefits of both plugins with minimal changes to the nest.nvim format.
