Hi there, It seem that the only add-on to Apple Mail application out there (truePreview) is a dead project. At least, the developer does not answer any of the requests posted on his site... As well, this is not a included feature to not have mail automatically marked as READ by the MAIL app if the Preview Pane is activated... That was the bad side. The brighter side is that the TruePreview source code is open and available on his site. I was wonderiiiiiinnnnnnnggggg....... Would there be any charitable person to fix the issue with the source code of the software... Or if anyone already have a alternative to this problem.... Note that the delay feature that was possible to set before has been disable by Apple.... Snif snif, please help..... P.S: Sorry for my poor english writing.
