Integrated font matcher (whatthefont)
When converting customer-supplied logos into vector artwork I often need to match their fonts (sometimes easier than others) I use the website whatthefont which does a good job, a feature like this would be very useful within illustrator. Select the area of an image click "find font" and illustrator suggests what it thinks are the correct fonts, either within your own font list, adobe fonts or other external websites.

I was thinking if I had a tool to pull a color out of a ready picture.
Why don't I have a tool to pull the font type out of a ready-made image?

Yeah, some collaboration with WhatTheFont or WhatFontIs could be useful.

Select outlined type or a photo of a typeface (rasterized type and the app matches it to the nearest similar font in the library. It could offer several options but it will never say "sorry no similar font found." You could even draw a character and it would find the closest font to it.
This is valuable to anyone in production who is asked to make changes to outlined or rasterized type or when the client doesn't provide the font name (which they never do) or the client says "can you use Buscemi Bold and you don't have it. it will find something close enough. I worked in an art department where we spent several hours per week trying to match fonts. This feature would have saved a lot of time.
