Thanks @Jhonnyr97 sorry for the delay!
I generalized a little the method taking inspiration from @sambarza here (cheshire-cat-ai/docs#66 (comment)). The idea is to grant access to the plugin obj, from which you can get path, id, save and load settings easily.
utils.get_current_plugin_path not needed anymore

Now we can do from within a plugin:

cat.mad_hatter.get_plugin().id # gets plugin folder name
cat.mad_hatter.get_plugin().path # gets plugin folder path
cat.mad_hatter.get_plugin().load_settings()
cat.mad_hatter.get_plugin().save_settings(settings)
