Yes, I use all of the icons that are in my editor. I already removed the ones I don't use. I'll use the full screen as a work-around. But, it makes the workflow a bit awkward.
Otherwise, I'm very glad you reverted back to the way it now works (more similar to the old version) instead of the live view when it first launched for J4.
BTW – there's one other bug in the Text Block. If you switch to the code tab, make a change, and then switch back to the text tab, and then save, it doesn't save the changes. It requires that you make the change on the code tab, then save OR make the change on the text tab, then save. You can't move between them.
