Don't think toooo hard before you post to the forum... we love to see your crazy ideas in their raw form. But do consider running Check Style and Analyze (PyFlakes) as they find simple issues (like your unused variable) and push you to make your code more readable. I have become big fan of autopep8 on my Mac. It would be cool to see that level of automatic reformatting as an option in Pythonista.

Hmmm, actually, I made a few other small mistakes for it to be all view/orientation friendly. The ui.TextField in search panel and ui.Label in footerpane; did not have their flex attrs set.
If intrested, I hope this gist Fixes it. a lot of combinations to test

It's only half import, because can easily change MyDataClass, to point to some other simple data items or with a little effort use it for other things.

@JonB I changed the loading as you suggested and it works! Thanks a lot!
