I have a 1900s bungalow and I'm currently stripping off all the wallpaper in the house. I've got my electrician coming in to redo the service throughout the house then we'll be back in to repair all the walls which gives me a good amount of time to figure it all out. My plans for cracks are to stabilize the walls with the Plastermagic product (still considering plaster buttons). The outside corners in nearly all rooms have bullnose rounded corners and most if not all need some work.

Any advice!?
