After the finale? (Fallout 4)

I went for the Institute, in general, I’ll say that I already knew everything in advance .. for this supposedly "plot" of theirs is predictable. But that's okay, the essence of the game is not only in the plot, there are also enough side quests. I played over 100 hours. It seems to have climbed everything, although not all areas are open .. now there are tasks from the Minutemans repeating, and a quest for a psychiatric hospital ... I was in the Alliance, the quest there was carried out to search for Synths allegedly. In Damon City, I also took all the quests. For reinforced concrete and underground, too, I took all the quests .. but I interrupted them all now they supposedly are not. The question is what to do after completing the plot, where to go and where else can you get quests, asylum 114 was there on the instructions of the plot .. they write what else there are shelters, who will tell you where to get quests?

Another question is how to make a shelf for dolls?
