We are continuously working on improving our existing themes. The Material Design Guidelines has been updated recently (see the What's new
section) and we will consider Material theme update in our future releases to match the Data Tables' styling and other UI differences.
Regarding floating labels as well as any other interactive behavior ( e.g. animations and transitions) we are still on the research stage of how and if possible at all to implement these without affecting the default behavior of Kendo UI widgets with other themes (different to Material Theme). In other words, this interactivity cannot be handled by the CSS theme files only and require additional JS code and changes in the way widgets are rendered. This will affect the behavior of the whole Kendo UI framework and as such we might not be able to build-in these features. Yet we might consider providing external solution, if these are widely requested.
