Why were theme variations removed from version 2.0?
Because Internet Explorer can only read a finite number of external style sheets (approximately 30), and because RapidWeaver publishes a separate external style sheet for each Theme Variation, it was necessary to remove the least important Theme Variations from Flex 2.0 to ensure continued Internet Explorer compatibility. RapidWeaver 5.0 will introduce CSS consolidation, a feature that will enable me to reintroduce these Theme Variations at a later time. If the removed theme variations are important to your websites, I strongly encourage you to skip Flex 2.0 and wait until Flex 3.0 which will reintroduce these variations when RapidWeaver 5.0 supports CSS file consolidation.
