Well done, Nigol!
epUBFixer is so intuitive and easy to use.
I recently added
"back links" to footnotes by manipulating the toc.ncx using ePubFixer. It was easy to do and allowed much need navigation for my (crippled) ADE hardware reader without a touchscreen or back button.
I started with a well-coded epub called 'Lorna Doone.epub' by AlexBell available in this thread
Blackmore, R.D.: Lorna Doone. v2 03 Oct 2010
I moved all chapters listed in the TOC Editor screen onto the "Lorna Doone" heading and created level2 TOC entries for the chapters (I had to add another link to chapter 1 from the Add screen). This was just a cosmetic preference of mine.
Then, at the Add screen, I (shift) selected all the anchors listed under "Footnotes.html" and then choose "Select Next Text" for all of them to better describe the footnotes! I moved them onto the TOC Editor's "Footnotes" heading and it created level2 TOC entries for same. I even renamed those level links via (shift) select and rename using "[1] - %T" to add the footnote number back.
In the Add screen, I then expanding each filename listed and moved the detected footnote "back anchor" like "[1]" and moved each one, in turn, onto it's corresponding newly added footnote level2 TOC entry. This created a level3 TOC entry for each level2 TOC footnote!!! Then I mass renamed them using ctrl-click with "%T - back to text" and it changed "[1]" to "[1] - back to text"
It was a bit tedious, but employed very simple drag 'n drop, point and (shift/ctrl) click as well as only minimal typing!
Attached, please find my fixed version of the original "Lorna Doone.epub".
I hope this inspires others to get
fixing .epubs using ePubFixer!
p.s. I attach some screenshots of my work
