Thanks for playing the game and the suggestions. I'll take them into consideration.
You can post feedback and suggestions on the discussion board of the steam page.

Regarding lack of space:
Town territory can be expanded by placing down Storehouses (they act as mini Keeps). You may have to clear out some neutral camps though.  

If trees are blocking your building space they can be deleted with the delete tool (The big red X in the construction panel). You can pretty much delete any trees on the map with it.
