For some reason, WordPress has removed the underline button in the editor. I can bold, and italicize, but not underline for some reason. I have zero idea why there was such a burning need to eliminate this pretty basic feature of an editor. I suppose I can go in and manually add in html codes, but why bother with an editor if I have to do that kind of cr*p.
Evidently it’s been so long since I felt the need to underline that the disappearance of the button didn’t draw my attention at all.
That said, almost any deficiency in WordPress can be addressed in some way or another, and usually it’s via plugin, which it is here.
