oh, yeah baby, let's dance ;)

yup, basically just the data() function returning the proper data from grouper 
given a "row number"

yep, writing bindings for drag and drop is on my todo list (iirc there could 
even be some properly licensed code out there, i have to check)

another thing that could be tricky is the tasks popups (basically means un-
parenting some components from the root component, from some experiments i did 
with extenders, it *seems* to work, still have to see eventual countereffects, 
since really bad things could happen inside the declarative engine ;)

yes, for sorting we can even just move the task widget, and maybe initiating 
the drag only when the cursor goes out of the taskbar...

well, my qml skills are still basically figuring out everything that is not 
possible, and each weakness discovered, shouting doh! :p

so i still can't assure you it will be possible to have a 100% feature parity 
(consider that when deciding about writing the model or not :p), to me, it 
looks like very near tough, and worth trying (we want scenegraph right? just 
look at how it's insanely freaking
