It would be just a little aesthetic enhancement: when you add an attachment to a note, the icon near the attachment will be not “J” but the icon of the type of file.
Yes I’m thinking about changing this. For files I think I’ll put a generic “file” icon for now. For note links, I’m not sure but I’m thinking about putting no icon at all. It’s just a link after all so there’s no need to make it look different, but I’m open to feedback on this.
I like the fact that a link to another note is denoted somehow. It does not have to be the J icon, but it should be marked somehow. Maybe this could be optional via a setting.
This can already be customized via css
I agree with @tessus.
Also (for unnaturally fussy people like me!) having an icon for non Joplin links would aid formatting / layout.
I have a collection of links; some internal, some not. It produces a “staggered” list.
A suggestion could be to have just two icons; one that indicates an internal link to a Joplin note or resource (currently a “J”) and one that indicates an external file or link (like Wikipedia does).
I suppose that this could be extended so the internal link reflects the type of resource it is pointing at (which I think is what the OP was referring to) but it could get out of hand with all the 1000’s of file types someone may want to attach to their note.
maybe also add some extra icon for PDFs ?
For files, there are a lot of sets of icons. For example, here there is a huge set of icons. The icons (not the vscode extension code) are licensed under the Creative Commons - ShareAlike (CC BY-SA) license and, given that they are all .svg. all together have 3MB size.
I don’t know if the license is good for you.
