Change casing to sentence case for titles, headings, labels, menu items, and buttons
Problem
Maybe the intention is to use title case everywhere but it looks unnecessary.
Proposal
Since this is already using some buttons from the Pajamas Design System why not also adopt some of the punctuation guidelines, too?
Use sentence case for titles, headings, labels, menu items, and buttons. Use title case when referring to features or products. Note that some features are also objects.
This means that button labels should change from Account Settings to Account settings, Edit Selections to Edit selections, etc. In contrast, step marker details can remain as is (e.g. Source Connectors, Source Selections, etc.)
