I'm stuck and need help. Under File > Document Properties. I need units to be displayed inches. Whenever I make the change, and save it, it's back to mm when I reopen the document. I've made the changes and saved it under the templates folder. It saves details like border settings, page orientation,...

Each time I try to use the perspective tool I get the error message

"this extension requires two selected paths."

I have the most recent version. And I'm trying to apply the effect just like this.
