ios8 custom keyboard extension

Apologies in advance if this suggestion is already posted. I didn't do a search. I love the new app extension with ios8 and find it very useful. However, there are many applications that don't yet integrate with extensions as well as other occurrences where secure notes and other 1password pertinent information would be useful to integrate without leaving what you do, going to 1password copying and pasting workflow.

So to solve these, a custom keyboard may be useful? Same idea as textexpander applies for their keyboard only in this sense, it is a secure keyboard, requiring touchID authentication when you activate it and giving you the ability to interact with your 1password database from within the application you are in as part of a standard keyboard interface.

Just throwing it out there. This would make the ultimate integration point and is something that I will be looking forward to see if you put under consideration.

Thanks, Avi
