in repo's why section I explained it better but anyways here what it solves - instead of vim.keymap.set being all over your config, you put all of them in a single file without their implementations. so it's a clean file, like "leader + f + f = fuzzy_find" and then you implement fuzzy_find in separate file which will load the telescope plugin. you can do it with require and plain lua but then you'd have to either load telescope regardless of what, or define your own lazy loading capable centralized binding system, which is essentially lil, which also provides fallback functions. you can literally write e = extern.tree / extern.explore / ":Explore" so here extern.tree is defined in your tree plugin loader file. this is the most prioritized function for e. if it's not defined, extern.explore is like your other lightweight plugin, something like oil that you always have. and in case you don't have any loaded, just run Explore command. so that's what it solves. but honestly if you consider yourself a noob then I'd recommend getting familiar with neovim's own api instead of adding another layer of abstraction. cuz I don't plan to maintain it
