I love Samsung's built in photo editor but it lacks one key feature that I really use a lot on my photos.
Sometimes I have to send a lot of images to someone in a resized format and I really have to edit each picture one by one to select resize to e.g. 60% resolution.
I would love to have this functionality built inside the gallery so that we can quickly multi select the images and click resize.
It will save us space as well as make the process fast.
