Is Microsoft still committed to SharePoint Designer?
- They are committed to it being supported for SharePoint 2016 and SharePoint Online. There will be no new version of SPD coming out in the future.
I heard there would be no SPD 2016?
- Correct, but SPD2013 works with SP2016.
Anybody creating design packages for SPO with something other than SPD?
- You can use the Design Manager in SPO or SP2013 to create a Design Package containing Master Pages, Page Layouts Alternate CSS, Display templates and more.
What and how? Anybody doing it manually with plain editor?
- Check out this tutorial for Design Manager
Any concerns with custom master pages based on Class Oslo breaking in SPO 2013 and MS constant updates and changes?
- If you are using SP2016 OnPrem, go wild with master pages. You control when the feature pack gets installed and can test before launching any changes that could impact your custom master pages.
Modern Experience updates?
- There are no master pages for the Modern Experience.
Possible to create custom SPO designs for Modern Experience?
- Presently we have very little customization options for the Modern Experience, but they are on the road map.
