Beta review: I too could not find the Board button that used to be at the top. But until I discovered it at the bottom in the icon floater, I made do by adding my BOARDS as cards and left them in my inbox as a left side panel visual card button (does that make sense) I am visual. I love it. Made it work. Then all my inbox cards arrive on top.
I really like the INBOX. I have automated my Outlook to send any email with keywords 'Revisions' 'edit' 'resubmit' to my board and the card is just built, summarized, and sometimes even a checklist is added with all attachments. wild. So thanks!
I guess this isn't how Inbox was expected to be used but its a pretty neat solution. This is why I love Trello so much. What other tools offer the same flexibility for people to find solutions to their problems?
