Hi,
Your requests are on our radar as we recently started focusing on Drawings again and you can expect new functionalities over the course of the next half year. Options to reach the goals in No.1 and No.3 are coming soon step by step. Templating solutions for No. 2 are a little further down the roadmap, but also actively considered.
I would be interested a little bit more in your multi-sheet drawing habits. When you work on multi-sheet drawings, typically how many pages do you create? Are those different part drawings of an assembly or does it happen that you break one single part drawing into multiple pages?
