Is there any way to perminantly add my own icon sets to Obsidian so I can use them in plugins like "Editing Toolbar", etc?

What I’m trying to do

I really want to be able to use icon sets other than Lucide all over the application, specifically the plugin Editing Toolbar.

Things I have tried

  1. I’ve searched the forums to no avail.
  2. I’ve tried Obsidian Additional Icons
  3. I’ve tried Obsidian Custom Icons

It appears there are no plugins that allow you to add a bunch of custom icons or install additional icon sets for use with styling plugins or other aspects of the app. It’s nice that editing toolbar lets you input custom SVG code for a toolbar icon and I use this currently, but it would be much nicer if there was a way to add additional icon sets to the app so you can select them in the built-in icon picker.

Am I missing something? Are there any plugins that allow this? Is it possible? I’d be willing to code my own plugin if someone can point me in the right direction.

Thanks for any help.
