Did you have some specific customization options in mind? The ones I can think of right now would be the line types, buy/sell characters and formatting/coloring of the lines.

My idea is here All 4 lines and placeholders

Default:
-"%account%"
-"%amount%"
-"%sell%:%buy%"
-"%Item%"

Would also like some flexibility, its more important to me to see whats in a shop than who owns it. My preference would be:
-"%Item%"
-"%amount%"
-"%sell%:%buy%"
-"%account%"
