Apparently Android 4.4 is using <title></title> tags for push notifications. Also some clients like Outlook might allow you to view email in a browser for better rendering. In those cases title tag would be useful. At the moment I haven't figured out any way to add custom titles for templates.
Can't it be part of head-attributes?
<mj-head>
<mj-attributes>
<mj-title>My title</mj-title>
</mj-attributes>
</mj-head>
Or of mj-head?
<mj-head>
<mj-title>My title</mj-title>
</mj-head>
It will be add into mj-head as you mention see #307 ! :)
