On the menu, when you want to re-read the file information, it would be 'nice' if they was a checkbox to regenerate the screenshots.
The most common reason I want to re-read file info is that I have a better copy.
On an aside, as an 'online' collector, I've found that the process to store some of the information I'd like to keep isn't obvious. I guess that comes from the program trying to meet the demands of so many people. At any rate, the solution I've come up with is to use bookmarks and the wish / seen checkboxes with a custom language file. This allows me to colour (yes, I'm Canadian) the movie list so I can see what I have yet to download, what I need to check (ie. a download 'might' be a better copy, but it's unknown at the time), and whether I consider my current copy to be satisfactory (ie. video quality is OK and audio is English).
In addition, I've found that using the QUALITY setting in FILE INFORMATION allows me to make specific notes that can be grouped (need better video, hard coded subtitles, need English audio, etc.). This was a wonderful thing to stumble upon.
One of the problems with such a flexible (albeit wonderful) program is that sometimes the solutions aren't immediately obvious. Through discussion, perhaps we can refine some of these and create a FAQ (better yet, template) that makes such things easier based on the specific interests of the user.
Sorry for the posting multiple topics in a single thread.
