We are aware that the Photo Album is a well used and useful app, but that it could do with a bit of a usability overhaul to make it more friendly.
We've talked (elsewhere on these forums) about some changes around the photo titles, and the ability to upload several without having to Zip them would be beneficial.
Unfortunately I don't think there's anything we could ever do about the right clicking thing, though I'll note you're other suggestions to feed into development of the Photo Album app.
There are already some significant improvements to the layout of photo pages planned as part of some new theme development (though currently the functionality of the app itself is not scheduled to be changed).
