In some browsers (including Arc, Dia, Firefox and Zen Browser), Cotypist can only show its suggestions in a "mirror" window above the text field rather than in line with the text itself.
However, it is possible to enable inline text suggestions in Arc and Dia (but not Firefox or Zen Browser) by enabling the Text Metrics accessibility feature. Follow these steps:
chrome://accessibility in Arc.
Important: Cotypist will only be able to show inline text suggestions in Arc for as long as the chrome://accessibility tab remains open. You can simply leave it open in the background.
We understand that keeping this tab open is a bit inconvenient, but given that it can simply be left open in the background, we hope it's not too much of a hassle.
