You can sort articles in Newest First or Oldest First order and additionally by All or Unread only.
Elytra has 4 sorting options to choose from, where sorting is done by the published date of the article: 1. All - Descending (Newest First, Default) 2. All - Ascendeing (Oldest First) 3. Unread - Descending 4. Unread - Ascending For the Unread section of the apps, the 1. and 2. options behave like 3. and 4. Your selected option is applied by default the next time you open a feed. When searching, this option is ignored and articles are always listed in Descending Order.
