Something to help with browsing for a mission:
The details of each mission should probably have the Points value included, and to browse by points range.
Set up bands, for scenarios that might make it into tounaments Standard Play (100 to 125 pts), specialised missions (sub 100pts), Large Dogfight (150 to 200pts), Extreme or Epic (200+ points).
It helps make the browsing of games easier, if you don't have alot of time/models, it's an easy way to quickly pick something - or on the flipside, you want an afternoon's play and looking for something big.
