Is there an issue with rolling sifrei Torah on Shabbat in preparation for Yom Tov? Would the tircha detzibura override any hachanah or quasi-hachanah concerns?
Well, someone could always get to shul early on Yom Tov morning, so not really tircha detzibura. But if you read (not keriah, just read like from a chumash) from the section you rolled it to, then you are using it on Shabbat. You can even point out to someone some interesting feature, like how the days are each a separate paragraph. So you are rolling it to learn from it.
