Add "add row" button for IIV?

[antoniaih]

Since it is possible to delete rows in the IIV table there should be a button to add parameters to the table. Otherwise deleted parameters are lost and the user has to start from scratch.

Why should it be possible to delete rows? Isn't the check box enough?

[antoniaih]

I think the main idea was to make the table less cluttered in case of a model with many parameters, e.g. a model with many transits.

Many transits still only have one parameter extra so I think we should remove the delete button and always list all parameters.
