Stalwart refuses a blobId in a card's media ("blobIds in media is not
supported"), so adding or changing a photo always failed. The editor now
saves the photo as a data: URI, which Stalwart accepts and returns
unchanged, and leaves the card's other media as it was. Checked live on
0.16.22; the mock now refuses a blobId the same way.
Avatars in the mail list come from the address book's cards, and nothing
loaded those at sign-in, so a photo showed only after Contacts had been
opened. The cards now load in the background at start, the avatar uses
whatever cards are held, and a shared card's photo is fetched from the
account it belongs to.
Fixes#376.
Right-clicking a sender, or any address in the message details, opens a menu
offering to add that person to the address book - plus edit them when they are
already known, write to them, or copy the address.
"Add to contacts" opens the contact editor prefilled rather than saving
silently, so the address book gets a real card that the user can complete,
not a bare email address. contactFromAddress splits the display name into
JSContact name components: "Ada Lovelace" into given and surname, "Lovelace,
Ada" unpicked, a single word as the given name, and a name that is really
just an address left off entirely.
Addresses in the details block were joined into one string, so they are now
rendered per address to be individually targetable.
ContactEditor previously ignored a prefilled name on an unsaved card - it read
name components only when the card had an id - so it now reads them either
way.
