We changed the expandable pane on the right hand side of a blist to include useful details about that blist: when it was created, when it was last edited, who it is shared with, etc. You can still add new columns from there as well, just like you were able to before. This is a nice and obvious improvement:

Yes, it’s free!
In the future we will introduce a premium version of blist, designed specifically for businesses, with advanced features and near limitless storage. The exact pricing hasn’t been determined yet, but the premium version of blist will be attractively priced.
Even after we introduce the premium version of blist we plan to continue to offer blist for free to consumers. The free version will be as feature rich as everything you see in blist today.
blist used to have a slick and cool black, glassy color scheme. We’ve revamped the look and feel of blist to greatly improve the readability, reduce eyestrain, etc. We’ve replaced the glassy black, with a lighter, more muted gray, as well as increasing the font size throughout the application, so it’s easier to read your data, and easier to read it for a longer period as well.
