EPUBs to Kindle on Fire

I transitioned my preferred reader to Kindle for Android when Amazon’s Send to Kindle became easier to sideload EPUBs. I have always like the Page Flip ability. To me, it feels more like reading an actual book. I also appreciated the seemless Dictionary, Translate, and Wikipedia as soon as I highlight a word. I have found I much prefer the Highlight and Note functions on a tablet compared to my Kindle Paperwhite. (I need a swipe keyboard.)

Prior to this transition, I was reading EPUBs on my Android tablet using FBReader. I liked its ability to upload books to Google Drive and the ability to quickly see metadata and summary in Book Info.

When I read Kindle books I enjoy the Time Left in Chapter.

If I convert an EPUB to AZW3 in Calibre and sideload it to my Kindle Fire I get:
• Time Left in Chapter
but I do not get:
• Page Flip

When I send an EPUB to Kindle on my Fire I get:
• Page Flip
but I do not get:
• Time Left in Chapter

Is there a straightforward way to get both when I read EPUBs on my Fire tablet?
Similarly, is there a way to migrate metadata to Kindle’s About this Book?
