Separating View from Data, Plugins, Modularity

Hi,
How modular is Discourse internally? Will it easily be possible to develop a plugin which uses a different approach to discussion for a certain category?
Does Discourse use the MVVM principle or something similar, so that a discussion tree (or network) can be displayed in a different manner than it is now?

Basic example: Show Discussion as a tree rather than a list (this is not what I want to do)

If not, is it planned to achieve more modularity?

これらは非常に漠然とした質問ですね。「どれくらいモジュール化できるか」については、Customization > Plugin ディレクトリを覗いて、人々がどのようなことをしているかを見てみると答えが見つかるかもしれません。その後、以下の初心者向けガイドをチェックしてみてください:

PS: Discourse is an Ember app powered by a Rest API, so yes.
