On a FullHD screen, when clicking on the subquestion relevance equation (multiple textboxes, need to check if for others as well), the text box that appears is very small while the box for the answer option is very long. The small box makes it difficult to work with the subquestion relevance equations, even if they are fairly short.

Surprisingly, when you make the browser window smaller, this text box becomes bigger (see screenshot).

I also think that when there is a relevance equation entered, this box should always show (otherwise you will overlook that there is a relevance equation, or the symbol should at least change color so it is clear behind which of the answers there is a relevance equation.

Additionally, relevance equations don't seem to have immediate effect (javascript not triggered)?
