I always thought it would be cool if spell slots didn't increase with level and instead simply grew in power.
A first level wizard might have 3 major spell slots, 3 minor spell slots, and 3 cantrips. As they level scaling would work by slots changing their tier. Eventually minor spells become cantrips and major spells become minor ones. By 9th level , the wizard might have 3 major slots (5th level spell equivalents), 3 minor slots (3rd level spells equivalents) and 3 at-will cantrips (1st level spell equivalents).
How does this tie into balance and resting? Well, wizards in 5e already recover some spell slots on a short rest, we just need to expand that concept. Arcane recovery can simply recover one major spell slot and one minor spell slot per short rest. No more spell level limits or daily limits.
These factors combined would allow wizards to regain a decent amount of power back from a short rest to effectively extend their adventuring day. The reduced total in spell slots that the major/minor/cantrip slot devise provides would prevent wizards from dominating every single encounter and also reduces their nova potential. Having fewer spell slots and having more of them recoverable with short rests also makes them more easily balancable with short rest or at-will based classes.
