Create a tiny icon to match the icons in the sidebar

[JacobDB]

This is awesome, I used it to create a nice "Repositories" icon for my Mac. I do have one small request: Would it be possible to add an option to create a tiny icon in the style of the Downloads icon as well? I'd really like a little Git logo in my Favorites rather than a dumb folder

Do you know how to set an icon that will be used in the sidebar? I think I once looked into it, but I didn't get very far.

After a little research, it appears that this is not a metadata/resource fork property of the folder, but specified by applications by creating Finder Sync Extensions.

Should be possible, but it looks like it'll take a whole bunch of grunt work.

Ah, so more difficult than just generating an icon. That's disappointing. Thanks for the info!

I'm sure we could still do it. ;-)

I want this so much !
Maybe this could be useful: https://github.com/nullobsi/SidebarICNS ?

For what it's worth, I've wanted this for a long time as well and I have found this project: https://github.com/rknightuk/custom-finder-sidebar-icons
It automates the renaming process mentioned in the readme of the SidebarICNS project and also implements the guide from the Reddit post.
