Adjusting your text size from within an article

Our current text resize feature allows users to change the text size of content from the app settings page. To review and then possibly change it again they'd need to switch between the article and settings pages.

This change would allow users to adjust the size from the article they are currently on, likely via an icon in the toolbar, making it easier to get the size right first time. The option from settings would still remain and the two would be synced.
