How replace the default file icons for new ones?

Is there a way I can replace Nextcloud’s default file icons, for new ones with a different look?
I just don’t feel the default ones look good enough. Kindof look like toy icons a bit, my humble opinion.

I’m assuming Nextcloud reads those icons from graphics files, and if one replaces the default icon file with a new one, it would change sitewide.

Any tips or suggestions greatly appreciated.

Based on the following issue ticket, which seems to be related to your request, this seems not to be possible yet.

@j-ed Thank you.
I have a feeling your suspicion is correct too. I will wait for a future version before I try this again.

So curious to know if there’s been any changes to this since it’s been a long time since the last post on here. I just joined Nextcloud and I really want to customize the icons to use the Phosphor library instead, but I’m having trouble figuring it out. Here’s a link to the Phosphor library.
