Encrypted private key:
Encrypted private key that is stored locally so you have to insert a password to unlock Nostrgram. This is a really neat feature that adds some extra security and privacy.
Hoping to get a finger id added to the mobile app down the road so I don't have to enter a password everytime
Performance and findability:
I find scrolling through and searching on Nostrgram a very great, fast and smooth experience. Try go to your own profile and scroll down to see your own history, loading very quickly. The grid layout also makes scanning for content faster, but it takes time to get accustomed to vs the vertical timeline.
Translate tweet:
On every note there is a translate note button. Nice addition.
Download history:
From your profile you can download a json file of your event history. Not sure if this effectively backups, is it your timeline? If someone know, please reply.
Layout switching:
You can choose between multicolumn, instagram, twitter, pinterest layouts.
Feed modes:
Global feed.
Following feed: Show notes by following, or by what's recently liked (COOL).
Friends+ : People you follow and the people they follow (also cool)
