Mail: Add filter condition for iCalendar attachment
If an email contains a meeting invite, it shows up in the message list with a specific icon (silhouette of two people), similar to what happens if the message has an attachment (paperclip icon).
However, in the Advanced Search dialog, there is no option to search for messages with meeting invites (even though I can filter by the presence of attachments).
Is there something obvious I am missing? Is it a simple case of "Oh, we forgot to add it to the Search interface, gimme 5 minutes", or is it something deeper?
