Task management is a whole area separate from note taking. This was something I was interested in many years ago but have not been able to publish a system to implement my ideas therein. Since people generally seem to be happy with Org's todo and agenda features, we expect to just interact with those from Hyperbole.
But for notes, yes, one needs to capture them quickly and then get back to your former context. Later on you can process them more fully.
Although I see the great utility in having capabilities on mobile devices, I find most apps way underpowered for constant use. As Emacs becomes more usable on mobile devices, we can add more mobile-friendly features to Hyperbole.
