@Vlad I just found this issue because I couldn't find it, too.
IMO the icon does not convey the meaning of "feedback". I actually don't really know what this icon is even supposed to convey. A dog with a green checkmark in the background.
I never really realized that there is even an icon in the top-left of the sidebar, and if I'd have seen it I probably would think that it just takes me to https://kagi.com
The link should either be in the list down below where all other links are, or the icon should be something which conveys the meaning of "feedback/bug report".
e.g. literally a bug (insect), speech bubble, thumbs up/down.
Or create a unique kagi feedback favicon that you can use everywhere for kagi feedback, so it has a "brand" and people will faster recognize this. This would also "solve" a feature request I submitted a while ago 😉 https://kagifeedback.org/d/1875-use-another-favicon-for-kagifeedbackcom
