I hope Apple Passwords integration will ever make it into Orion. The iCloud Passwords extension from Chrome/Firefox store doesn't work anymore with Orion and it's a total blocker for me.
I would even go so far as to recommend to replace the native Orion Password manager with default Apple Passwords integration, which enables also automatic sync of passwords to all iDevices. Orion is a Mac browser after all and there is not so much a reason to re-invent the wheel in my opinion.
