Quote - - Most importantly, please bring back the ability to mouse-over a thumbnail to bring up the stats on that image (views, comments, etc.). The new "eye button" is much less efficient. - There is a lot of wasted space on the page where an image is displayed; the previous design was much more efficient, requiring much less scrolling to get to the comment section.

-The comment section is much harder to visually scan. Before, the commenter's name was displayed below his avatar; now they are separated. And again, there is just way too much space between sections, between comments, etc

I totally agree... the previous gallery was better.
More efficient and pleasant to see.
This design has lot of wasted space (the comments boxes are huge) and now I have the not-so-cool feeling to browse Tumblr. Not my intention to be rude, but I hope its NOT a change made to meet the requirements of tablets and smartphones. Lately a lot of sites are jumping on that bandwagon... LOL
