Sorting features for the wishlist

[LiquidAcid]

Inspired by the thread about sorting of the marketplace albums...

I would also like to request some new features for the wishlist:
1) Sort by album release date
2) Sort by user-set priorities

Why these would be good features:
1) Nice to see which album to buy in the next time (>=5 years on the market... might be OOP in the month)
2) Some sort of "move up", "move down" system to prioritize the albums.

One should be able to somehow save the priorities, so sorting by album release date doesn't destroy the previous sorting.
