I thought on a next upgrade it might be an idea to customise the width of text boxes.

At the minute they are customised by how many cells they are spread across. However can you make it so there is an option where, like an image, the amount of cells it covers is the maximum width of the text box, but a lower width can be applied.

e.g. a text box covering 3 cells each 100px would be a text box 300px wide, but a customised width of 265px can be set. Possibly with text box justification option, this does not mean text justification.

i.e. should the text box, rather than the text inside, be on the right, center or left of the covered cells.
