Along similar lines, I would like the UI of Hive to have more flexibility, ease, and beauty.

Oh and also, when creating a post, the side-by-side (which I like) reverts to top-to-bottom where "side to side" means left side typing while right side is preview and "top to bottom" is same concept but with preview on bottom, which is less efficient with space since most of us have more horizontal resolution than vertical.
