I find these org mode re-creations in other editors neat but the problem always seems to fall to the fact that other editors can't properly support org-indent-mode as they lack support for virtual text or because of other problems.

In org with org-indent-mode mode the following text:

  * Foo
  ** Bar
  baz

Is rendered as:

  * Foo
    * Bar
      baz

This visual indentation and separation is, at least to me, an important feature which helps when reading.

It is basically a must-have for any org-mode re-implementation (I'm not just making up obstacles here, I daily-drive neovim and like the idea behind the org-mode plugin for neovim but I've tried it multiple times and it just doesn't work for me).

There are also probably many other shortcomings too.
