Why I Use Only 2 Vim Plugins

Vim without plugins is unusable because there is no behaviour for commenting lines line in Textmate or Sublime

Why don't you use telescope?

If i had to pick only one plugin it would be vim-sneak. Motions to find text like fF and tT but matches on 2 letters. This is so good it should be built in.

Do you use netrw? How to make netrw easier to use?

I agree, we don't need million plugins for Vim. Some of there are just there to replicate things from other IDE that we don't need. But my favorite plugins are those that extend the builtin capabilities of Vim, those ones really understand the Vim philosophy.
