The release notes for 10.1.4588.0 includes the following new feature:
Added option to create temporary alias with Ctrl-Shift-N in compose window
This sounds like it’s now possible to manually type the from address instead of having to select from one of the predefined account addresses. But when I do a Ctrl-Shift-N in the compose window, nothing happens.
Wow thanks that works, thanks! But why did the UI designer make it so unintuitive? Simply adding a button to edit the already selected option would have been so much better
Anyway glad we finally have this feature, it’s been sorely missing.
