- Pattern match on the Mode

- Dispatch drawing/events to the corresponding widget/s

module should only contain:

- how to draw non-widget information. For example the footer

the elements, otherwise you'd be focusing on a non-existent widget with unknown result (In theory the code is safe unless you have an empty section list).

- To build a SectionList use the safe constructor sectionList

- To access sections use the lens provider sectionL and the name of the section you'd like to access

modify the vector length
