The help text for auto-hiding the ribbon is very hard to read, due to lack of contrast in the dark UI mode.
Maybe the descriptive text could be a bit lighter? Or equally light, but use a moderate bold for the headings…
But I love the new integrated version 4. I hope giving away AS works as intended – I think it’s a great idea. I’ll be sending links to a lot of people. Discovering SE as a plugin to AS has already made some friends more interested. It’s tremendously easier to use this way, especially for those of us who eschew Word.
