When I open a document created using a font that I don't have, I want the opportunity to replace all instances of that font with another. This process is pretty straight forward in Illustrator and even Flash, why can I not find this in Photoshop?
Oh yes. This is a MUST. I have been constantly frustrated with the lack of this feature. Those who work on collaborative PSD files with multiple layers and complex font styling really rely on this ability to keep the file integrity intact.
I am currently experiencing continuous Program Errors because PS can't reconcile duplicate fonts available to other apps and make a choice and stick with it. This, and a combination of Suitcase Fusion issues, makes life even harder.
While we're at it, I'd love to see ATM come back out again - your font management software was the cleanest and simplest to use on the market, but that was 15 years ago. : )
