Thread:Support/Writing special characters in the new interface/reply (2)

I don't know, what ULS is, but while I am typing these words, I have a list of clickable special characters and character sequences below the editing field:

We had that once with message editing, too. If I'm not mistaken, we got three new versions of editing meanwhile, with this most useful feature disabled, or missing. I would like to have it back, or something similar, and I am truly sad that I do not have the means and the capacity at the moment to add it to the new editor, if possible.
