Feature Requests: Multirow Colorful Tabs

Sir, I am very happy with this addon. I am no computer geek and use pc for web surfing & internet bookings, thats ordinary applications. have been using it since years. Might be due to generalised use I wont be much demanding in colors & lines for Tab Differentiation, but would request you to incorporate a feature to incorporate multiple rows of tab say upto 3 or 5, as well limit the number of tabs in a row. It makes the differentiation a lot easier, when you get more of header to read. Currently my FF3.6.6 opens 12 tabs in a row but its all very short header. I like to limit the same to 6 or 7 in a row and three rows or max of 5 is i desire, with free internal tab transport from any row to any. this would save me from installing those big add ons of Tab Management, whose most of the options are not understood by me or maybe us ordinary pc users.
