Love it! I think we need a different visual for the link attachment however. instead of the mime type, it should show the link itself along with a tooltip for the entire thing (do the other attachment types have tooltips? they should!). also, I think instead of the paperclip icon it should be the link icon. otherwise, this is looking solid!

@csells updated the visuals now for link attachments. The other attachment types already have tool tips so didn't touch on that. I implemented attempting fetching the links favicon and if not found then it falls back to the default link icon. Heres a screenshot of how it looks:

That is above and beyond. Well done! I'll do a merge tomorrow and a release next week with some others I'm working on.
