Either, that I was not logged in in ChemSE, or did not pay this much attention when I did, but just a few moments ago I noticed a change of ChemSE's layout. While writing this question to ChemMetaSE, I can't but notice this seems to be equally affected:
Call it just a personal taste or conservative approach, yet in my perception, moving the five categories Home, Questions, Tags, Users, Unanswered from a horizontal alignment into the vertical one of a column eats away much of screen estate. The central spot, about the questions, looks more cramped than earlier, I think. In addition, the previous horizontal alignemnt of the five categories was accessible regardless of the location in the question's preview.
It seems to be an issue seen with mail providers like Yahoo and Gmail, or data bases (reaxys did something similar months ago), but here the question: is there a way to revert back to the "classical view" and layout?
