It's kinda strange.. with the vast amount of people using the WordPress platform one should think that someone had mod it in.
Personally i've modded so that you see the current albums Title when your browsing it (aka when one see all the thumbnails) and i've also added a simple "Go back" under it so that people more easily can well.. go back.
Oh, and i've also edited the dashboard to include a simple step-by-step guide on how to add a gallery, change image size of the images in that gallery, set the watermark etc etc.. so that new users OR people that are just aren't that good with computers more easily actually can begin using the Nextgen Gallery via that guide. :)
Those are just simple hacks though. The current-gallery-title -thing feels very important though since it's so much more clear if people hotlink directly into a gallery or just browse it in a normal fashion.
