As of March 2023, with the New Acrobat, the Page Thumbnails have been moved to the righthand side of the Acrobat interface. Please allow changing this to the lefthand side again, as an option, without having to revert to the "old" Acrobat.

I'm pretty sure I won't get many votes for this, and I'm pretty sure that the UX designers won't want to consider the change I request. I do want to relay that if the "old" Acrobat ever goes away, I'll switch to other software. Having the table of contents on the righthand side doesn't make sense to me. Acrobat is the one-off that is different, which is why it is such a pain. If you can convince other application developers, including those for Word and PowerPoint, to also switch to the righthand side, I'll gladly adopt the new Acrobat.
