We have an existing application that was developed with ExtJS, that we'd like to move to AngularJS+KendoUI. The only thing that's holding us back is that you don't have the ability to created editable PivotGrids. That feature is available in Sencha's product, and our users use it extensively. 
Ex: http://examples.sencha.com/extjs/6.0.2/examples/kitchensink/#rangeeditor-pivot-grid

In some applications data will be so huge to load on PivotGrid, and the manipulation of filtering, reordering and changing dimensions between rows and columns take a long time, freezering the browser for a moment. With data paging this frozen time is avoided.

Connection with Azure Analysis Services not work.

If i have a hierarchy location, for example country, city and postal code, i can only use location as field and can't use country, city or postal code. If i want to use them indiviually i would have to configure them as extra attributes in the olap schema.

It would be nice, if these hierarchies could be used as fields.

Advanced functionality in xml/a binding should be available to local binding. Also ability to define new binding protocols.

Provide support for virtual scrolling.

when data present inside the array which are binding to pivotgrid read method then not an any issue BUT  When if one of the empty array binding to pivot grid read method after that wherever we try to bind the array with data it causing problem 'Cannot read property 'value' of undefined'.
