I'm making this post to see if there is any general interest in a patch to reduce (not eliminate) the size of the top header menubar thereby reducing what many have described as 'screen wastage' in kepubs.
In the last few days I've been tinkering with
pipcat's alternative method for patching the
nickel file. I discovered that it's currently quite easy to reduce the height of the top menubar. See attached images for example.
First image: a typical kepub page on an AuraOne with GeoffR's 'Custom Footer' patch plus my 'Reduce Header by 33%' patch.
Second image: same page when tapped to show top and bottom menus. Without the 'Reduce Header' patch both top and bottom menubars are 13mm in height. With the extra patch the top menubar is 8.5mm.
In truth the height could be reduced to any number of pixels you like, but I chose reducing by 33% as a first stab.
What I'm not sure about is whether those who describe the top header in kepubs as 'waste' are more than happy to just use the 'full-screen' option. In which case I won't bother pursuing this.
If there is any interest I can use GeoffR's
makepatch utility to create a suitable 4.1.7729-specific addition to
nickel.patch
