The 4 Fixes I Need...
-I need the Front End to dynamically load on the Back End so I can see it, in order to format Front End writing in real time.
-I need the system to save work automatically so I do not lose it accidently.
-I need the buttons and fields of the system laid out better and making stable. {They tend to move independantly)
-I need the video to automatically generate a thumbnail on the menu page.
