I totally agree and take it a step further. The rich text box is in serious need of help. It needs an undo button (maybe even a redo button). The link maker looks virtually unusable. The selector for changing text to titles and back is weak. Also, like paxaurora6 said, the lack of spell check is alarming. I’m setting up a writing platform for my clients, one where they can share what they write publicly. I feel really bad that they won’t be able to spell check right in the box. They’re going to have a less than convenient time changing to titles, and a hard time adding links. This will be a turn-off for my clients, in turn, making them less likely to stay subscribed.
I’ve been a writer for years and would shy away from my own writing platform because of the RT box. It should be more like the one I’m using to type this right now.
