Vlad I think that the wording "device-aware" is little dense while skimming on this sentence.
When I read "Customize Kagi to look..." then my attention will instantly drop: I think that I already know all this sentence. But it's obviously false: I didn't look closely too to the "device-aware" thing.
So: maybe would be sufficient to put the highlighted sentence on his own, spaced from the first words...also substituting "device-aware" with "per device" and embolding it, would make it clearer.
