Modify Kobo Aura/Touch Home Screen

I have asked this question already in another forum (GUI Plugin - Kobo Utilities) and Davidfor suggested to ask it here:
Is there a way to remove or change one or more entries from the "Library" option on the home screen ?
Eg: I don't like "Articles from pocket" / "Previews"
and delete them or instead
I choose a shelf from "My Collection" just like "Python" or ....

Thanks for your advice -Peter-
