Well,I shared whatever I knew.Its not at all that I don't know anything. There were certain obligation for softwares to pass my tests and these three softwares which I have suggested were the only one in Windows to pass the preliminary tests. (I can't use a Rolls-Royce Phantom,if it does not have wheels,even though its one of the most comfortable and luxiorious cars.) The advanced features are worthy to be tested only if I get satisfied with the basic tests. Come on,in painter,if you paint gradient or apply flood fill on a drawn space ,it won't fill completely at edges.Now what's the point in testing advanced features,when even basic features won't work properly in Corel Painter. Hence,I do not know each and everything about photoshop ,but it has passed my basic tests. (I had only demo version,whose licensces have expired.I had a very old Cracked version,but I don't want to install any illegal versions on my new Upcomming Tablet PCs,as far possible.) Anyway,I like the new features you have discussed above.
