Support treemacs-ext with nerd-icons instead of all-the-icons #823
Description
Describe your request
Somewhat recently doom dropped all-the-icons in favor of nerd-icons.
As part of that some of the extra visual tweaks present in doom-themes-ext-treemacs.el, like hiding the modeline for example, seem to have been lost.
What do ya'all think would be a recommended fix? Add a new extension for treemacs-with-nerd, split out treemacs-ext to separate icon handling from the rest, add additional conditional logic to existing treemacs-ext to just skip the all-the-icons stuff?
Briefly explain its use-case
Using doom with treemacs.
