Hello!
For those interested and having spare time, I started a project of UI
components for Amber inspired by AngularJS two-way data-binding; those
it is different and more Amber/Seaside compatible.
It is still in early stage, but maybe it already approached the minimum
viable product stage - it has primitive one-way binding already working;
on top of plain Amber widgets for view part and wrapping plain objects
for a view model.
If you want to make a few experiments, you can find it in
