Deleting duplicate parts bins?

Not ‘simple’, but possible. I reported this as a bug recently.

Duplicate part bins

To fix, you need to manually edit the config file while Fritzing is shut down to remove the duplicate entries. The entries are all numbered, so make sure the final result is all in sequence. Renumber entries if needed.

The bug was reported against version 0.9.4, but I believe the config file is the same for the older version.
