I didn’t mean reading files in general.
I meant reading in files that, in previous versions of Knime, needed that checkbox to be read.
So if you could read files before with the csv reader, but not anymore with 5.11 - that is a problem.
File Reader might be an alternative, but then it is a breaking change for existing workflows (which would be a big pain to fix, in my case).
Therefore the option needs to be restored (or be enabled in general, even with a missing checkbox).
