Add/Manage meta-contacts via Menu
problem
The only possibility to create meta-contacts is via Drag&Drop, which is broken for me via #7881 (closed), and might be inconvenient and/or hard to discover for some.
analysis
A different means for managing would be convenient.
enhancement recommendation
My first thought would be a context-menu option (maybe in the "manage contact" submenu) to unfold a contact, creating (or showing) a Meta-contact with the current contact as child - one could Drop other contacts beneath that, without needing the context menu which is usually shown and broken in #7881 (closed). AFAIK this is how pidgin does it.
Another way would be a context menu option "merge into contact…", followed by a dialog/... for selecting the other contact. More easy to find, but might be cumbersome for many contacts.
