It can be very hard to really see that much in the game, and i think visibility should be improved on buildings and the whole map and villagers in general for better controll.
I suggest optional icon on villagers/Buildings/Building projects.
The whole map is covered in fog, and i can hardly see anything.

The whole terraform system could work, but i think it should be automated for buildings since building placement becomes annoying if it is not automated.
Roads is a Feature that is very difficult to manage in this game, because buildings and workspace is not at the spot of the building, and therefore becomes a nuisance if you just have to cover the whole map and ruin the ground with dirt roads.

On a Personal level, i think Roads should just be removed from the game altogether or changed into something different.
Roads worked in banished because of the flat terrain and better visibility.
But in a middle age simulator like this, i think roads should be created by the peasants themself over time when they walk on the places they often go to and vanish over time if not used.
A road system like that, would make the game feel more realistic and immersive for a medieval village simulator.

And much much easier to manage, dont think many people care much for roads or the whole terraforming thing you have to do before placing buildings.

That is my opinion on the things in this game that should be worked on, to reduce the annoyance level of the players.
