What prompted you to write your own, rather than going with something like (the excellent and liberally licensed) Handsontable?
There are currently 571 open issues[0] for Handsontable on Github. Each new release breaks something major and we can't wait forever for them to fix the issues. I wrote two blog posts regarding this (without mentioning Handsontable, but it was the library in question):
* http://lauris.github.io/development/2014/08/25/work-and-open...
* http://lauris.github.io/datazenit/2014/08/29/open-source-wor...
These articles may shed some light on why did we start development on our own library.

Any plans for developing Sensei Grid past what your use case requires? I hear all the cool kids get to paste cell ranges into their grid plugins :)
Sensei Grid will be kept simple, but additional functionality will be provided through plugins. I don't want to flood the core grid with functionality that would lead to complexity. However smart pasting is something I would consider including in the core.
Btw I just updated README.me file and added goals, blog posts and other info related to Sensei Grid - https://github.com/datazenit/sensei-grid/blob/master/README....
