I would like to Suggest more colored themes
There are many themes we can change background colors on, or even use an image as a background on. > http://theme.wordpress.com/themes/features/custom-background/
Give us a box to change our Text colors :) (without having to hunt HTML stuff and copy-past ) .
These are 3 ways to change fonts on WordPress.com blogs. Take note of (2)
(1) Changing font families, colors and size in text in posts or pages either post by post or page by page by coding into the HTML editor. http://en.support.wordpress.com/editors/font-size-color/
(2) Changing font colors in text in posts or pages either post by post or page by page using the #4 icon (Select text color – change the text color) in Row 2 the Visual editor. http://en.support.wordpress.com/visual-editor/#row-2
(3) Changing all font families, colors and sizes throughout the whole blog by purchasing an annually renewable Custom Design upgrade and using Typekit Fonts with Staff support. http://en.support.wordpress.com/custom-design/
Note: A few themes do provide for changing font color in the Blog Title and/or optional Tagline and/or links. In the majority of themes font changes to font families, colors and size in the blog title, tagline, menu, post titles, page titles, categories and tags, widget headings, comments, and links cannot be done without CSS editing.
Add a Youtube kinda of Widget
We can embed youtubes into pages and posts and also change the width and height attributes, place them in text widgets and display them in our sidebars.
