I don't speak Japanese so all the titles of the various anime don't mean much to me, even when in romanji. So at the beginning of new seasons I usually have to go down the list of Latest Uploads and click each one to see if it's an anime I'm interested in or not.
The feature of hovering over a title and getting it's main picture would be useful in this case, a feature that is currently implemented in the search function. For example, instead of having to click each title in the Latest Uploads section, I could just hover the mouse over the title and the anime's main picture would appear and I would immediately know if the anime is one I am watching or not.
I like the idea of just being able to hover the cursor over the anime link and having it's main picture popping up but at the same time it's just as easy to click on the entire link and get a good synopsis of the anime as well as the main picture. Although aesthetically pleasing, I'm going to have to disagree with this suggestion.
