- TextBox is a superset of Paragraph, so Paragraph is deprecated - adds support for a cursor, which can be moved - the `Text` field is now private, replaced with `SetText`, `InsertText`, and `ClearText` methods TODO: - adding focusable widgets support to termui might clean up the API since we could potentially move the event handling from client side to library side - add support for scrolling the TextBox view - fix the cursor position on linewrap - fix linewrapping - add line number support
