In the mobile app, it would be good to be able to create threads by sharing content from other app's.
For example, Tweet, item in a To-do list (Google Key / Tasks), Message on Facebook, WhatsApp message.
You would 'share' the message or item in question, then the GetBusy app would be offered as a destination and you would create a To-do from that content. Could use the existing 'Create To-do from comment' style mechanism, but would likely need new text to say it was created from something else. Or could simply create a To-do / Note with the shared content as the description.
This would make using GetBusy about 100 times more useful as could move other messages/things I need to do into GetBusy to manage them.
