Hello,
I noticed that the Snackbar Titles (as you call it) is not always arranged the same depending on the application in Groups, Pages and Events.
This bar is located on the second column, or across the all width of the page.
An exception for Albums where this bar is absent for Title.
Personally, I find that the best layout is that of Videos and Audios Applications.
The left column for navigation, and the right column for title and content.
The "New Video" and "New Audio" button is more accessible and clearer by being first.
I invite you to see screenshots as attachments.
Thank you,
Philippe
