wp_editor() issues

i like the wp_editor() but it either still has a few issues need fixing or i am doing something wrong. i understand that it will not work in all themes but it also has one issue that i can see in the Twenty Eleven theme. the issue is if you use the dark version on the visual tab because it uses the background of the page what you write inside the text area you cannot see where on the html tab it uses a white background so you can see the black writing. also i have notice that on another theme that does not support the function everything works fine except for the part you click on for the media upload. i am using this function in a plugin and if i add wp_enqueue_script(‘media-upload’) to my plugin then the media upload works without a problem. one other problem i have is no matter which theme i use editor_css will not change the style for me on the editor, i am using a link in between the style tags. if anybody has any ideas on the issue or a tutorial either please post a link here or update the codex. thanks
