Sure, I just thought we should perhaps design or create the 
compatibility with Kylix in mind.
Isn't it true that Delphi 6/7 is compatible with Kylix (i.e. in case of 
colors they use the Kylix/CLX design), and therefore if we stick to 
pre-Kylix (Windows only) design, we will be obsolete by the time of release?
