I personally prefer reading on Portrait Mode on my 2-in-1 and it gets awkward when I encounter a Landscape Page. I mean yeah I can just turn it sideways but I prefer to just have that as an option, that's kinda how I prefer it anyway (Weird how the Official Weekly Shonen Jump Reader offers this but not other readers). I mean Portrait Mode has a good advantage of ComicRack not having to load/process the page (Reading on Double Page Mode on Landscape there is a brief period where the page is adjusting to the much smaller resolution), having a much higher resolution without sacrificing page real-estate.

Ideally I would prefer if I could just have the page be displayed in their full-size then zoom out so that all of the page gets displayed. That way, Double-Page Spreads would still take up the whole vertical space... but IDK it seems that they never implemented zooming out on Comic Rack.

My current-work around way to do this, forcing Double Page Mode, setting it at Fit-All, Zooming in at 200%. It's not perfect, sometimes you will still get the occasional stray blank page that's caused by using Double Page Mode and not Double Page Mode (Adaptive), but using Adaptive Mode will then have your One-Pagers improperly zoomed in (IDK if anyone has a tip to make ComicRack behave differently for One-Pagers vs Two-Pagers that would be much appreciated).

And I guess it would also be pretty good to know if there's a way to improve Auto-Scrolling smoothness but idk that's just a personal thing, I do like all the nice bells and whistles ComicRack has.
