Windows. Latest FDM.
When I try to create a new section when there are already 20, I get "Cancelled." A lot of times, I would like to have more than 20 sections. I think this is really a trivial mod for the developers (maybe make it an "advanced" feature so people don't mess up.
This happens on all network connections and no matter how many mirrors I have.
