Feature Request, New space between written areas

Hello. I would like to make a feature request. I want to be able to create an empty space in an already occupied area. For example i need to add new information to page 5 but notebook is already used till page 20. Sometimes i need two more rows, sometimes half a page. Creating a new page is too much and breaks the flow of the notes.

Another thing would be having more colors available in landscape mode, there is unused space for it

Thank you for the hardwork :) Notewise has been very useful for my complex note-taking
