I've played the EA about 3 times now, and know I can safely alt-tab for a few minutes as soon as I reach the druid grove attack and Alfira's song, for instance.
As of patch 5, you can skip the initial grove fight (unless you mean only the initial cutscene before the fight, that can be skipped with spacebar, same as other dialogues). I use a familiar to trigger that fight, since it has 1 hp and therefore is easily killed (or just remove it from the battle by resummoning it outside of the combat zone). That way the fight will play out without your party. You can go adventuring in the chapel in the meantime. Same for the druids - tiefling fight. I have not tested the goblin raid, since that would require joining with the cultists.
Alfira's scene should be made skippable (if it cannot be skipped, haven't tried), I agree.
