I have already said my thank you personally, but I write it here also.
A couple of days ago in an email to them, I suggested something. I asked if the notification I would click on in top right corner, (bell icon) which brings up list of read, or unread items associated with your blog, if by chance they were able to make it slightly darker, as I was struggling to see the difference between read and unread items. I see now they have done this and it makes it so much easier to tell what is unread and read now.
Thank you WordPress. 🙂
