Impress lacks an option to copy master slides. When creating presentations with more than a single master, all formattings have to be done for each master slide again. This is elaborate and fault-prone.
An option to copy existing master slide with all formattings would increase usability of Impress a lot.
Steps to Reproduce:
1. Open Impress
2. Switch to master view
3. Try to copy a master slide
No option to copy master slides (only to create and rename a slide)
Option to copy a master slide preserving all formattings
User Profile Reset: No
As this is an enhancement request issue is independet from any releases.
