In case I encounter any issues with my randomizations using this display format

You won't do this, as long as you do it correctly.

I mentioned this because some strange ideas occur that require something like "two groups  with four questions inside another group" or randomisation of pairs of questions which are also randomised, etc.
 

@holch I display the survey group by group (what's the best practice?). Thanks for the side tip on format as well. Not sure what exact exactly is wrong because I also found the font in Joffm's screenshots too tiny, but from my preview end, it's legible enough (using Georgia default size). 

I am not referring to the actual font size. The size is readable. But what I am referring to is the "blob" of text, without line breaks, paragraphs. There is no structure.Look at joffm's screenshots. There is one long text.

I would give the text a better structure, with paragraphs, bullet points, etc. This will make it more readable and easier to grasp for respondents.
