Using the add card into the conversation button is now very hard, I cannot see the search field, so I'm just guessing what's up there.
Is it my device or have I somehow hidden it?
It's been integrated into the top bar, and appears magically (open book icon) in the upper right, next to the magnifying glass when you are in a message/text entry field.
Oh no, I found the button, I just can't see the search field. {Gone}
More on this.
I found if I change my view back to list mode rather than any of the picture ones I get the search field back.
That has been my work around so far.
It should be fixed by 4.2.1.
Sweet :)
