There's an edit button. After clicking it, another window opens with all file naming schemes and a preview. This is a useless window. Everything could be done better, because now we have to click too much just because to edit a naming scheme. The way is too long.
The "Add, remove" buttons in the file naming scheme window could go to upper level, so we'd have in the main window:
CODE
Output file name format:
[the formats name ] [edit] [add] [remove]
[the formats name ] [edit] [add] [remove]
There's enough room for the 3 buttons to be right beside the dropdown. So we'd have all functionality on top level. There's the big preview window below it, so we do not lose anything.
