Not your imagination. Scrolling does seem to be slightly improved, as does general performance (loading times, number of crashes, etc.).
Still a lot of stuff I'd like to see them add, however, such as auto a-z sorting of files (so I can use DSFTP to transfer things more often without massively disorganizing my card), an option to turn off icon display in the file list, a "favorites" system of sorts (so I can access my most-played games more quickly), and, most importantly, an option to allow us to load our homebrew of choice in place of the god-awful PDADS/G6 Moonshell variant.
But oh well - it works! Who am I to complain?
