resizable <textarea> is generally quite a limited thing. It would be significantly more useful if we would have universal <frameset>: <frameset cols="200px,*> <select type="list">...</select> <textarea>...</textarea> </frameset> so to have split views. Resizable textareas are quite trivial to implement with barebone JS but such split views require native support from browsers in order resizing to work effectively.
