It's nice to see Pocket is continuing to add new features exclusive to Premium subscribers. In the 6.2 update released today, Pocket has introduced 7 new fonts (including two of my favorites – Whitney and Ideal Sans), plus controls for line height and margin width. There's also a new Auto Dark Mode setting (which could be a nice companion to Night Shift on iOS 9.3).
I've been trying Pocket again because of Recommendations (you can follow mine, too), and I had already bought a Premium subscription last year, but I haven't found much utility in the permanent archival and auto-tagging functionalities. More typographic controls is something I deeply appreciate, and I hope we'll see more Premium features this year.
