Dired-omit-mode in parent directory and preview panes?

[gekoke]

Is there any way to also apply dired-omit-mode to the parent directory and preview panes? I understand if it might not be feasible due to using ls as a listing tool.

I would like this too. Ideally, I would like for the preview pane to be a stylistically the same as the parent directory (i.e. start in omit mode, include coloration from dired+, include all the neat dirvish-attributes, etc).

We've got the option to Preview directory using exa command, but it looks like exa is no longer maintained and is continued by the actively maintained fork eza, which I'm guessing should just drop in.

But regardless, I'd rather not have to add another external dependency, especially if it's possible to re-use dired's functionality for a more seamless experience.
