Sorry, I didn't explain myself very well, but I do totally understand what you mean. After you use "Editor" to compose a post, there used to be the small "Raw HTML" symbol at the upper right hand corner. Now that's gone.
So justifying text, images, adding lines, etc. cannot be done anymore which is a big problem for me. To the best of my knowledge, I don't think you can used "Editor" to do this.
Is there a possible workaround to this until an update is released that fixes this issue? Well, I hope it gets fixed, lol.
I bet a lot of this stuff can be done in markdown, but I'm not familiar with markdown at all.... So I guess I'll have to learn.
