I use rockbox on iaudio x5. I recently updated rockbox after a longish pause (previous version was from early January 07, just after the new MPEG player but before the latest menu reshuffle).
With the new version (today's Daily, r12756-070314) I can no longer insert single files into a playlist the way I used to.
I use the file browser to navigate to file "a.ogg" in directory "A" and select it. Result: as with the old version, a dynamic playlist containing all the files in directory "A", with file "a.ogg" playing.
Then I select another whole directory "B" (not a file inside it), raise the playlist menu and choose any of the "Insert" options. Result: same as it ever was, a dynamic playlist containing the files from directories "A" and "B".
Here's the difference: When I go to another individual file (call it "c.ogg" in directory "C") and Insert that, it isn't inserted. Instead, the old playlist is erased and I get a new dynamic playlist containing only the files from directory "C", with "c.ogg" playing.
Is this a bug in rockbox or in the user who missed an interface change?
