*Cough* realistic aero bars effect then achievable *cough*
OH also
Chat Tab Left, been thinking about it, and obviously it expands with whatever size tab you chose, whereas top tabs won't change the tab bar size, so maybe we'll need to add in chat tab bar left small,medium,large sizes too, just to get stuff REALLY perfect
Thanks Patch
lots of love to you!
btw, did my postcard arrive thanking you for shirts yet?
