Clara HD Menu change issue

[AJMK]

Hay All,

I am having "issues" with my Kobo Clara HD Menu.
Was hoping somebody here can help me with it.

The 'problem' is this:
The Home-menu does nothing for me (esp. dislike the big 'take the tour').
I like the Library-Menu much more and it would be nice if my ereader started with that Menu.

I added the line 'SideloadedMode=true' under [ApplicationPreferences] in the Kobo eReader.conf file (found that info on Wikepedia) and after reboot: Hurray !! No more Home button in the bottom menu.

But the fun was not for long.....
Anytime I turn on Wi-Fi and do a sync. (checking updates or loading new books from my Google-Drive), the SideloadedMenu is set to false.

I tried to make an entry in NickleMenu to set it manualy back to 'true' but it seems I do not know the correct code.
I tried:
menu_item :main :Reset Menu :nickel_setting :toggle: SideloadedMenu
and
menu_item :main :Reset Menu :nickel_setting : SideloadedMenu : toggle
But that does not work.

Any ideas?
