The reading footer is the area at the bottom of the screen where the page number or other progress indicator is displayed. The
`Custom reading footer style` patch allows the following properties of the footer to be changed:
- Footer height (the amount of screen reserved for displaying the footer),
- Font size used for the progress indicator,
- Vertical position of the progress indicator within the footer.
(In some firmware versions it is also possible to change the font face used for the progress indicator, although that can sometimes be problematic.)
In general, the default values for the patch result in a footer of about half the height of the one in the unpatched firmware. The same footer is used for both the EPUB and KEPUB reader, but as the KEPUB reader has a large header matching the large original footer, the smaller patched footer will probably look too small when reading kepubs.
Note that other factors in the book's stylesheet can affect the size of the gap between the text and the progress indicator: line spacing, paragraph spacing, @page margins, widows/orphans settings, and others.
The screenshots attached (Glo, 3.15.0) show a sideloaded epub with the line spacing adjusted to get the text close to the footer in both cases:
1. Unpatched
2. Patched (default values for Glo)
