Possibility to change the height of the rows.

[vhcg77]

Hi! First of all, I congratulate you because this is a very nice tool, specially for jupyter notebook users.

Also, I would like to add a possibility to change the row height because I have a too long text to show on a limited column width so I cannot see the whole text. Instead, the ability to change the row height is a very good addition. Other way to solve this is, for example, give double clic on a cell to open it into a new window (For this feature, could be good to open many windows as cell you give double clic.).

Thanks!!
