Cycle through Status bar presets

Please create a new issue with your patch details/link etc and close that after they add the label.
And at the bottom of the issue request KOR maintainers to add user patch available label so that users who are looking for it can easily find it. Also mentioned in KOR wiki

If necessary add screenshots or screen-recording of what the user-patch does.
Visual impressions are best (i.e. also recommended for KOR pull requests) and you (as user) get immediate idea and interest of what it is all about without any extra mental-effort.

Thanks for the suggestions.
What tools are available to record video on a Kindle (I've seen some on Reddit)?
I could take screenshots, but that won’t work in this case.

Not sure. I'm on kobo and never searched for screen-mirroring, VNC, screen-recording stuff.
If recording from e-ink device is absolute necessary (e.g. to show E-Ink specific settings/flashes etc) then check if it works https://www.mobileread.com/forums/showthread.php?t=150434 then record from PC.
Otherwise use Desktop KOReader for screen recording.

Not sure if it's worth for the effort as most likely we're doing it for special use-case like this...Better simply just record with phone camera🫣

Here's a new version for v2025-04-52 and above (preset code has changed a lot). Here's the feature request.

I'm not sure I understand ?
