Thank you for a great review!
I printed out a copy and am going through it step by step to get aquainted with all the new toys. What a blast!
It is mind boggling that Erwin took all those suggestions, bellyachings and complaints and turned a really good program into this treasure!
My sentiments exactly but better expressed.
Joe.
(Sigh) I know, Joe, You have always been able to express things better than I could.
Ok guys … …
Two things I especially like in this release:
a. Moving the Font Validate icon to the Standard toolbar. Saves a step.
b. Making the Validation report interactive, visible and zoomable. I can wander through entire font without coming up for a breath or having to go to another view. Can see the results of a fix or miss right away.
Zooming to the error condition is a really terrific feature. Definitely worth the price of an upgrade. Saves a huge amount of time when correcting faulty fonts.
Thanks Erwin.
