Text highlighting

Say you have text that varies in length (such as song title), but can't read because of the device's wallpaper. It would be useful to have a text highlight (alike something you'd see in Google Docs or Microsoft Word) that behaves alike a rectangle shape (color, corner rounding, padding width & height, etc), conforming exactly to the length of a fixed font text instead of being a static shape.

You can do this using standard text and background BB code, so just write [bg=#FF0000]My text with red BG[/bg]

thanks a ton ;D
