I must admit I just discovered the blog filter last night by accident. That's cause I almost exclusively use grid view when using Steempeak. I do wish there was a way to easily implement the blog filter list, and other such lists for trending topics and such, for grid view. Maybe a bar that appears dynamically on the right or left side when the user moves their mouse over it? That way it doesn't obstruct the grid view but is still easily reachable with just the move of a mouse! :)
