Match UI to theme

It’d be nice if the UI elements that come in blue, dark, or light could match their colors to whatever editor theme the user installs and selects, like Sublime. The editor theme support (eg., TextMate/Sublime themes) for Textastic is good, but I feel limited in which themes I can actually use because of the jarring mismatch between the Textastic app UI and many editor themes.  Speaking as an iOS (iPad) user.
