Excel-like features

Awesome library! This is more of a feature request than an issue, let me know if you have other places for this that are more appropriate.

Are you planning on adding excel-like features to it, by which I mean things like:
- Select multiple cells by holding shift
- Go to the top / bottom / left / right by holding cmd (using mac)
- On right mouse click, have options like delete or add row or column.

This kind of functionality is in Handsontable, as you might be aware of. First and foremost I'm wondering if you are planning to become more like this, or you're more focussed on a different kind of functionality.
