 *Tiling Shell* supports importing and exporting its layouts to a JSON file. With this you can create your own custom layouts without the built-in graphical editor, or share your layouts with others! If you are interested into knowing more about the contents of the layout file check the official [documentation](./doc/json-internal-documentation.md).

+### Tiling context menu ###
+
+Right-click on a window to use the auto-tile buttons and the snap assistant from there! These buttons allow you to tile to the leftmost or rightmost empty tile, based on your selected layout. The "Move to best tile" button suggests tiling to the nearest empty tile to the center of the screen.

+### Smart border radius ###
+
+In GNOME, different windows may have different border radius. Drawing a border around the focused window is hard because it is not possible to know the window border radius. All the existing extensions just draw a border with a static value, making the UI less polished. Tiling Shell, **dynamically** computes the focused window border radius at runtime. Moreover, if you have an extension or anything else who customize the border radius, the focused window border radius adapts as well! This can be enabled/disabled from the extension's preferences too.
