Pomodoro and Productivity Tools – Why not more integration

I have taken a short break from building my AI Bot due to work.  Sometimes priorities take over.  Which led me to wanting to make a quick note.

 I have been using many productivity tools over the years: currently I use OmniFocus more than others.  I have tried Things 3, Todoist and other apps.  All very good and do things somewhat differently.

I am also waiting to see what happens with OmniFocus 3 this year.

I have also tried many Pomodoro technique apps on my computer or iPhone or iPad.  I love the way it helps to focus and chunk your time.

The question I have is why are the two practices not more tightly integrated.  I would hope that if I had a task in OmniFocus I was working on ( whether i allocate time slices or not to it ) that I could initiate a Pomodoro time window to work on the task.

All of the current productivity tools are lacking this integration point.  I do realize many people may not use the Pomodoro technique to do work but I would think that there is a large group of people wanting this functionality.

There have been attempts to integrate through things like Vitamin-R and other apps, but it is awkward and not tightly integrated in a seamless way.

I am still hopeful and holding back purchases until someone steps forward to do this integration of GTD and Pomodoro to allow us to be more productive in an active direct way.
