 Note that the navigation stack is saved to a file when Lagrange is shut down and restored on the next launch. This means the next time you launch Lagrange, you can still search the contents of past pages. However, navigation stacks are tab-specific, so closing a tab will delete its history as well.

+You may be familiar with XML-based RSS and Atom feeds from the web. The Gemini equivalent of these is Gemini feeds. A Gemini feed is simply a regular 'text/gemini' page that contains one or more links whose labels are formatted in a particular way. This makes it very easy to write pages that clients can subscribe to.
 => gemini://gemini.circumlunar.space/docs/companion/subscription.gmi  See "Subscribing to Gemini pages" for more information.
 
+Lagrange supports Gemini and Atom feed subscriptions. Atom feeds are  automatically translated to the Gemini feed format so they can be viewed and subscribed to like a normal 'text/gemini' page. RSS feeds are not supported.
+
 Subscriptions are managed via bookmarks. When you subscribe to a feed page, a bookmark is created and the special "subscribed" tag is applied on it. In the Bookmarks list, this is indicated by a ★ icon. There is no other difference between normal bookmarks and feed subscriptions — you may tag any bookmark as "subscribed" and Lagrange will look through it for feed-style links. The bookmark title is used as the feed title. This defaults to the top heading of the feed index page, but you can edit it to suit your needs.
 
 Feeds are refreshed periodically while Lagrange is running, and also immediately after launching if it has been a while since the previous refresh. You may also manually refresh all feeds via the menus or by pressing ${SHIFT+}${CTRL+}R.

+On Windows, an option is provided to use a custom window frame. This provides a more consistent visual style for the application. However, the custom frame overrides default behaviors of the window, so if you are a Windows power user expect it to not support all the special interactions. For example, when pressing the Windows+Left/Right key, the window is resized to take over one half of the screen. Normally, Windows would then prompt to select another window to fill the rest of the screen, but this does not happen with the custom window frame.
