2.) Crash and or freeze after Cue file import, while Cue files don't find the pertinent mp3.
Have not noticed this, I corrected all my cue albums in FB2K before i let MC look at them.
But i agree it should not happen, a helpful error message would be better.
3.) MC can't tag CUE tracks. It edits the CUE files (text) directly.
I would like MC to write directly to the CUE sheet if 'update tags when info changes' is ticked. Mp3cue plugin for winamp the first of its type that came out years ago could do this. FB2K does it flawlessly as well.
Other than that the bug that prevents me from moving to MC 11 is if once you have imported your cue album, analysed it etc. And then if you move the album, MC loses the cue files, it still knows where the big mp3 is but the cue entries are orphaned. That means they are considered broken links.
This absolutely needs to be fixed, a directory move within the MC tree happens quite frequently for me that i dont even think twice about it.
