I use the old Frequency UI which has a target window that shows that as well as distance to target, and some other useful tidbits, it's a nice simple wire UI, seems to be really low on generating aggro, but has some awesome features. I attached it here, not real sure how it works, but it is uploaded at least. File is called Freq_di28889.rar, it's the full UI though, I don;t believe the components work individually.
This is not my work, nor did I have any part in setting up Freq UI, so if he is still around and wishes it removed I will do so. This UI is also available on the MQ2 forums, along with several other integrated UIs, I just like the vast amount of INFO this UI gives, yet the simplicity of it to look at.
