Also enlarges post headings and gives inline code a background. Post body
text is text-xl, so h4 headings rendered at paragraph size, and inline
code only differed from the surrounding text by its font.

+If you can believe it, up until this release of Budgie Desktop, favoriting / pinning applications has been limited to our Icon Tasklist. With the release of Budgie 10.10.3, you can now favorite applications right in Budgie Menu!
+
+Right-clicking an application in the menu reveals a small section beneath it with an "Add to favorites" option, or "Remove from favorites" if it is already one. Alongside it are the application's desktop actions, such as opening a new window or a private browsing window, the same actions you would find in the Icon Tasklist popovers. Under the hood, the menu and Icon Tasklist now share the same code for these actions, so they list the same things in both places.

+#### Keybinds
+
+In labwc 0.20.2, it started reporting errors whenever `rc.xml` has invalid entries. Our bridge had been writing empty keybinds into it, so some of you saw that "labnag" bar on _every_ login ([issue #956](https://github.com/BuddiesOfBudgie/budgie-desktop/issues/956)). The keybinds the bridge manages now come from a template, and only keybinds that are valid get merged into `rc.xml`. Existing configs are cleaned up on login, and any keybinds you added yourself are kept. A keybind can also depend on an application being installed, or on a minimum labwc version, and is left out when that is not met. Distributions can ship their own template to customize the keybinds they provide.
