What can Drafts for Mac NOT do?
The initial release of Drafts for Mac is focused on capture, editing and sync. It will not support actions initially. We do plan full action support for the app in the future – but many can benefit from the ability to create, edit and access all their drafts on both platforms in the meantime while we work to complete the somewhat more complex implementation of cross-platform action support.
From Drafts for Mac Status Update. I think the statement from the “but many can benefit from” is the key thinking behind this.
