I've add a new patch `My 24 line spacing values` to the attachment in my post #7.

This patch is instead of `My 15 line spacing values`, the only difference should be that the line spacing sider will have 24 positions instead of 15, and I've increased the range of spacing values. If you would prefer fewer or more than 24 spacing values then I could possibly change that, perhaps up to about 40 spacings maximum. 24 just seems like a good number to me.

I have tested a version of this patch on my Glo with firmware 3.19.5761, but the 4.0.7523 version is untested, so if somethig seems wrong let me know.

Edit: As before, you might wish to customise the line spacing values to suit your device and reading preferences. If you are reading with a small font size you might find that increasing or decreasing the font slider by one position doesn't always result in a change in spacing. In that case consider increasing the step size between values.

For example, these values increase the minimum step size from 0.02 to 0.025:
Spoiler:
Code:
# 24 values for replacement, change these to suit:
#
base_address = 5DD260
replace_float = 0000, 1.0, 0.7
replace_float = 0008, 1.0, 0.725
replace_float = 0010, 1.0, 0.75
replace_float = 0018, 1.0, 0.775
replace_float = 0020, 1.0, 0.8
replace_float = 0028, 1.0, 0.825
replace_float = 0030, 1.0, 0.85
replace_float = 0038, 1.0, 0.875
replace_float = 0040, 1.0, 0.9
replace_float = 0048, 1.0, 0.925
replace_float = 0050, 1.0, 0.95
replace_float = 0058, 1.0, 0.975
replace_float = 0060, 1.0, 1.0
replace_float = 0068, 1.0, 1.025
base_address = 5DD3C0
replace_float = 0000, 1.05, 1.05
replace_float = 0008, 1.07, 1.0725
replace_float = 0010, 1.1, 1.1
replace_float = 0018, 1.35, 1.15
replace_float = 0020, 1.7, 1.2
replace_float = 0028, 1.8, 1.25
replace_float = 0030, 2.2, 1.3
replace_float = 0038, 2.4, 1.35
replace_float = 0040, 2.6, 1.4
replace_float = 0048, 2.8, 1.5

Mmm something's wrong. I factory reset and then i tried just the 24 line spacing patch, and the ereader reboots whenever i try to open a book.

Works fine if 24 line spacing patch is deactivated

Thanks for the quick report, I have spotted a silly mistake and have replaced the `My 24 line spacing values` patch in the attachment to post #7. Those three people who downloaded it before I replaced the broken patch, please download it again.

Edit: The new patch has one byte changed as highlighted below:
Spoiler:

# loop to load 10 vals from old table
replace_bytes = 5DD354, 31 4B 07 F1 80 01, 20 46 1A A1 29 44
replace_bytes = 5DD35A, 00 22 20 46, D2 F6 32 EE
replace_bytes = 5DD35E, 61 E9 02 23 D2 F6, 08 35 50 2D F7 D1

The broken patch had 22 instead of 32

It works now, thank you! 24 option for line spacing is great for me!

GeoffR, how about fine brightness control? The default is so annoying!

I'll have to hunt for that one. Kobo have changed the way that feature works I gather.

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.

The surest way to check would be to take screenshots with the margin slider at minimum and maximum.

In previous firmware versions, at least on my Glo and I think other devices too, each step of the margins slider equates to 2% of the screen width for each margin (unpatched) or 1% (patched.), so if nothing has changed the difference between minimum and maximum should be 16% (unpatched) or 8% (patched) for each margin.

Hello Friends, I was able to do this years ago on an older kobo, but that was 5 eye operations ago, I can not get my file to update my Aura One. Does anyone have a koboroot.tgz that works on Aura One 4.0.7523 - Mostly I'm concerned with removing headers and footers, and I will take full responsibility if anything goes wrong.

changes like the following look good..

My 24 line spacing values
Custom font sizes
Search in Library by default
Freedom to advanced fonts control
ePub disable built-in body padding-bottom
Custom page refresh options (1,2,4,8,16,32,64,128)
Custom kepub default margins
Set KePub hyphenation
Fix three KePub fullScreenReading bugs
Force user line spacing in ePubs
Fix page breaks bug
Default ePub monospace font (Courier)
Custom reading footer style - but as I stated, anything that reduces the wasted space going to header and footer would be appreciated.

Can the patch to allow the footer to be moved and the margin around the footer to changed be added? I find this a very useful patch and I would like to not have to lose it when the next H2O firmware comes out.

If you're talking about the `Disable reading footer` and `Custom reading footer style`patches they've already been done.

Or are you talking about something else entirely?

It may not help with the H2O, though, as that may be a completely different firmware version number when it arrives.
