I like how google search has a link to my gmail on the top-right. Would be great if there was a space in kagi to put links to gmail or fastmail or any arbitrary link. It would affect workflows by allowing people to link in their preferred email/calendar solution of choice.
User would click "Add toolbar link" or something. They would get a modal with a url and name field. They would save and then they would have essentially a bookmark always to that link always visible in kagi.
