You would not believe the amount of time some designers will kill ambling through their font lists. I never want to be stuck looking for a good font for more than 2 minutes at a time, because designing the thing is the job—not perusing albums of the alphabet on my work computer.
For this reason, I love font management, in a fiddly sort of way. I believe that it has improved my efficiency when I need to make prompt font selections.
If you want some practical font management advice, read my Creative Market article for seven rules of thumb. Later on, I plan to post an expanded take on the subject here to divulge more tips. ∞
