We should discuss how we can manage different plugins (one repo or many repos) and how is the best way to get them installed. A plugin installer could be nice. Please share your ideas.
My prefered way would be to set the User folder under git and use git submodule to add plugins (like you do it in vim). In this case the developer should change the behaviour of the plugin loading (all folders in the User folder should be scanned for plugins or as a alternative a plugin config file).
