There is a `dataset_adapter` in vtk that should speed up the vtk file loading: ```Python from vtk.numpy_interface import dataset_adapter as dsa # Get vertices as a NumPy array without going...

Editing empty sheet

5

As pointed out in #93 and #112, creating an empty sheet, editing it and using `to_dataframe` or `to_array` to export the result does not work. Because those functions are `Cell`...

Changing `row_end` and equivalent attributes does not update the cell range in the view

Remove `numeric` cell type and add `int` and `float` cell types. Also adding `d3-format` formatting, like in ipywidgets, instead of the Handsontable default formatting (using Numbro)

Handsontable uses [NumbroJS](http://numbrojs.com) for numbers formatting. It might be a good idea to implement our own number formatters using [d3-format](https://github.com/d3/d3-format), like ipywidgets and bqplot.

I would like ipysheet to go in the direction of static typing for cells. e.g. if a cell is of type `numeric`, it would not be possible to set a...

Overlapping cells

I am reconsidering overlapping cells support. I think it can be confusing for users, I find it confusing myself, and if we remove it I see possible performance improvements. Currently,...

Questions about code design

3

I might be wrong, but I have the feeling that the code could be a lot faster than it is today. Whenever one cell attribute changes, we recompute the whole...

It would be nice to be able to deactivate automatic column/row resizing, we need to find a way to do that with Handsontable, and make it optional for the user.
