Thank you for the quick adaption of the patch.

I enabled my usual patch mix and everything appears to be working fine.

Spoiler:

`Disable reading footer` - works
`Remove PDF map widget shown during panning` - works
`Preserve PDF pan position across page turns` - works
`My 24 line spacing values` - works
`Custom font sizes` - works
`Custom page refresh options (1,2,4,8,16,32,64,128)` - works
`Search in Library by default` - works
`ePub fixed top/bottom margins` - works

`Custom left & right margins`
not quite sure if it works correctly the margin increase between the steps feels bigger then before, but I didn't compared it with an unpatched reader yet.
