Contacts Issues
So Contacts issues is not on your list of categories for improvement...?
I have recently been adding contacts from emails but they are not appearing when I search for them. Repeating an addition gives 'contact updated' message!
Even more annoying is that after a mistype in the search field, using backspace starts deleting emails instead as the focus comes off the search field.
When composing a new email, addressing suggestions come up but often these are old ones, eg @ntl, not the current ones in contacts or even the most recently used.
Because I maintain websites, I often need to copy email addresses for other purposes but this can only be done when reading emails not duirng composing them. This worked ok on the legacy version.
Please continue improving Yahoo mail (I totally dislike gmail) but please test more and try not to break it!
