4.01 at least, does not behave in a civilized way.

Making sets involves some non-intuitive steps. Or maybe I should say the dialogs and descriptions are not intuitive. The app tells you that it will delete the originals you are moving so make sure you have copies. But isn't the new collection that FontAgent is about to make, a copy? I think rather than the app itself being faulty, the wording is unhelpful.

FontAgent promises to check all my fonts looking for corruption. And it does find some. So why must I put up with endless notifications during actual use, that this or that font is corrupt? I do a re-start for example and I then must tolerate endless irritating dialogs that a dozen or more fonts conflict with system fonts. Well, don't activate the dammed things then! I didn't ask you to activate them and they are not in my start-up set.

Besides, they behave ok after those warning dialogs have gone.

Auto-activate notifications are a pain. They ride on top of everything else and I must wait for them to disappear.

I moved all fonts except the system/library/fonts to a separate location to avoid inadvertently activating more than just my preferred start-up set. Yet my apps sometimes show me the entire set of fonts. Thousands of them! (On other launch occasions, FontAgent will randomly activate nothing, leaving me with only a dozen system fonts available to use. Very annoying.)

I also think the interface is poorly-designed. Panes too small to be useful, Appearance is boring system 9 style.

I have been using Macs since 1988 and I am not any sort of novice. Yet I am constantly confused by fonts in general and management apps like this one, in particular. i really really need a strong, professional font management tool. FontAgent Pro is not it. Unfortunately, I don;t know offhand of one that is what i want. But I'm determined to find it if it exists.
