Corrections

Topic 1, 2
I made the change, took it off the website and put it in the Preset section under the +Preset, +Playlist buttons, it was in a good location.

Topic 3, 4
It reloads because it needs the updated information so that it can create the preset correctly with all the information generated from the selected image.

Topic 5
The change has already been made, it just hasn't gone up yet, it's default upload

Topic 6, 7
Fixed
