The Pinterest-esque media wall for all the photos & etc. is a nice feature, and surely goes well with mobile design compatibility. From a user standpoint, my one request would be sorting options. Right now, looking for a particular image that I need to edit often means a whole lot of scrolling and “load more” clicking.
If the images could be sorted by name, upload date (or ideally, either of those), that would be great. I don’t know if this feature would be better to add on the existing media wall, or if perhaps another screen with a sortable list view including thumbnails would make more sense. Would something like this be possible?
