...basics such as opening a door in the street and entering a shop without the GM loading up a new area and taking the entire party there is a huge setback and forces me to rethink the design of the areas I was going to build and the campaign I was going to run.
The way the house / wall editor works in the world editor is that you have seamless transitions between exteriors and interiors. You don't have to load a transition into a simple house. You simply open the door and walk in and it's technically the same area and level as the outdoor area. The only time you'd need a transition is if it's a big dungeon, castle or cave or a house with multiple levels. Then you need a transition of they go up or down stairs.
