Increase size of text box / reactive textbox size

[marksverdhei]

How

Expand the text field either as a fixed size or reactively by gradually expanding the box as the user inputs text

Why

The (current) dataset is based on book reviews. This means that the classification task becomes a problem of distinguishing male and female writing styles. If the classifier should get any good results, I think the user should be able to write a full book review in the text field without it looking clumsy.

I did not realize until now that you could customize the size of this field. I still think it could be nice to make it react to text though

This might introduce an issue where you can't see the current prediction percentages without scrolling down. This will need to be discussed further before approval
