Maps used to be accessible on the Kagi Android app by clicking the link under the search bar. It however had a big problem that once you were in, there was no escape!
Okay technically you could go back back back back several times to get out, but there was no easy way out. Also it was harder to find than things like Assistant and Translate because it wasn't in the main menu.
In the latest update, it's been removed almost entirely! You can only access it using !m or after searching for something then clicking on Maps.
I think the easy fix is just to add Maps to the list of tools like everything else is. And in the Maps UI, give access to those links so you can later get out of it again without going back repeatedly!
