No columns option in Mail after updating to 10.9.5
Upgraded to 10.9.5. Now, Mail doesn't offer the Columns option in "view". Only the "Conversation" which I find inefficient and bulky for managing my loads of email.
Sadly, Mac is more and more looking to me like MS. Any workaround will be appreciated.
MacBook Air, OS X Mavericks (10.9.5), 1.4 GHz Intel Core i5--8GB memory
