Short description of error
Assume you are beginner....
You played with blender saved some userprefs and startup...
Somehow you saved with your preferences that auto-pack is enabled...
You started a new VSE project added some wav files (1GB) you save... a huge blend file.
How would you disable auto-pack feature ?
Exact steps for others to reproduce the error
Just use "File>>External Files>>Unpack into Files" and header says "... (auto-pack disabled)"
My suggestion is to add tooltip to the "Unpuack into Files" or think of something else (wiki).
I maybe the only one that was frustrated looking everywhere howto disable auto-pack but in my opinion its worth to mention it to the developers.
