Yes, I realize that. I've tried it. It still gives you a tiny field for composing THOUSAND character posts.
I'm bitching at you about your screen utilization priorities. Users do two things: They read posts, and they compose posts.
The Adv. Interface does nothing to enhance either. While you save a click not having to switch timelines, you give up a LOT of scrolling due to skinny itty bitty columns that are not resizeable.
And
The field for composing posts is just as pathetically tiny as it is in the normal web interface layout.
I would LOVE to see one interface, with resizable columns and some user options for the composition field.
That's all I got.
