Whenever there are multiple resource deposits in a newly established outpost, it is sometimes embarrassing to manually check if the prior construction is complete or not. Thus I would like to suggest either construction queuing or small pop-up messages for outposts. Selecting multiple construction options should automatically send the following options to the construction queue, just like in a normal city. Alternatively, just like when an outpost's population grows or when a resource is purchased by other players, it is also feasible to implement pop-up message: "construction complete." with magnifier icon, which teleport player's view to the outpost.

It is not an critical thing, but definitely help us to save a few turns in terms of managing multiple newly conquered/established outposts. 

Oh ! I've missed your post somehow, but +1 !

I've made the same suggestion on my feedbacks, I'd really like to be notified as well when an outpost has been constructed. I often forget about it and realize after a while I could have built resources extractor, or a harbor.
