It would be useful to be able to filter locations by exact radii from your set location, as recently introduced in Kagi's settings. The current functionality — when looking through the restaurant tab, for example — is limited to ranking waypoints by distance. But it would be better to set a specific distance that the user is likely to travel, given that the difference between 1.1km and 1.2km (as an example) is superfluous.
Individuals are likelier to plan their travel to waypoints by radii as this feels more natural/intuitive, especially when walking and cycling.
Location Setting

Distance Ranking
I can envision this being a pop-up mini-widget that displays when the distance button is selected, alongside an indication of what the central location is being assumed as (this is important because some users may not be aware of the location setting). Google Maps's implementation of this is by travel time and mode of transport, which is very useful, but as Kagi Maps isn't (at least yet) intending to provide directions a simple distance calculation would suffice.
There are plenty of existing tools that offer this — it is a common feature that Kagi Maps should replicate!
