easytables.nvim VS treesitter-indent-object.nvim

No, Neorg does not use the same markup as Org-mode. They use their own specification that is specifically designed to be different from Org-mode spec.

Furthermore, each item you have listed as a benefit to Org-mode is in fact capable of being done in Markdown via plugins for neovim, and probably other markdown editors, like Loqseq, Roamresearch, or Obisidian, much in the same way you speak of plugins that interface with .org docs.

So, my suggestion is that before dismissing a comment regarding a plugin that is unfamiliar to you, is to read its spec, and then try to understand why people would be perhaps dismissive of that tool, especially when it chooses to conflict with existing, more popular choices.

treesitter-indent-object.nvim provides a context-aware indent object to quickly select the part described with indent-blankline.nvim. I find it useful because the indent-blankline gives you a live preview so you can expect what this object will grab.
