It would be great if there was an easy way to change and check the font size of word/sentence stimuli that are being called from a spreadsheet. At the moment, I have to fiddle around with markdown within every single spreadsheet cell. Is it possible to set a font size for a given rich text zone so that anything that is displayed in there appears in that size?

It would also be great if I could check that the font size is appropriate more easily than creating different spreadsheets with different font sizes and previewing the whole task (which could be solved by a "preview screen" option as someone else has already suggested).
