Here is a method we've been using in place of 'Daily' resources by turning them into (Re-)Chargeable ones.
Characters start at the beginning of the day with 1 Charge Token each (we hand out poker chips to represent them), which can be used either as an action point or to charge up daily powers.

Once used a 'Daily' can't be recharged in the same encounter, but unused Tokens can be carried on for the rest of the day - with a cap to unused tokens by tier: heroic=2, paragon=3, epic=4.
An extended rest resets all tokens to 1 for each character.
This method has the following benefits:
