is there any way to slightly increase the default size of the text field area? Of course, I can resize it manually by dragging the mouse in the bottom right corner, but I would like the default area of the field to be a bit larger. I would be grateful for a suggestion on which file needs to be edited to make this change.
If so, you can edit the file application/view/common/data-type/literal.phtml
In the <textarea> tag at the bottom you can add a rows attribute, so for example make it start <textarea rows="5" rather than <textarea . And you can choose however many lines tall you want it to be.
