Starcraft 2: Legacy of the Void Discussion
The way Master Archives work is that it gives you access to every unit and upgrade you could have had at that point in the game. For instance if you did the Korhal missions before getting the dark protoss during the campaign you will have them in the Master archives. You can also change your units and ship upgrades before each mission.
Only thing I'm really wondering about is why nobody has managed to create an savegame editor (lots of resources would not be the solution to everything but they sure would help).

* Get notified when new cheats are added
* Request which games get new trainers
