i was wondering if it were possible for a wizard to increase the number of cantrips they can prepare each day, from what's given on the wizard's spells per day table. they don't get extra cantrips for a high intelligence, nor for specialization. are they stuck with at most 4 cantrips that can be prepared at once, or are there other ways to increase this number? (it occurs to me that a wizard could use a higher level slot to prepare a cantrip, but then i'm not sure if it would be treated like the regular slot or if it would be at-will like other cantrips.)
I'd let you prepare extra cantrips in 1st-level slots, and cast them at will, too.
