I have been using rockbox for a while and it proves to be really great.
However, many @books listened to "simultaneously" may happen to be difficult to handle.
Here's why [please correct me where I am wrong].
There are ten bookmarks. When adding another bookmark for a file, the last one does not get deleted. Effect? After ten bookmarks to one file all the previous are lost.
I can think of an improvement as an option to the current settings, for user who listen to many things interchangeably and use bookmarks in order to mark the last position - not for special moments.
Two additional, intelligent bookmark non-exclusive updating modes:
1. smart update by file
new bookmark to the same file deletes the previous ones
2. smart update by folder
new bookmark in the same folder deletes the previous ones
If later bookmarks exist, ask what to do.
What do you think?
