Since upgrading to 2.1rc1/Firefox4b10, the context menu option "Rename file from parent metadata" is grayed out. How can I fix this? Thanks for the help!
Yes on both counts. After some more examination, it seems that newly added articles are being automatically renamed, but some of the older items in my library still have uninformative names that I would like to automatically change to the same format.
The option should be disabled only if the attachment isn't an imported attachment (e.g., if it's a linked attachment) or it's in a group for which you don't have file editing privileges.
