 		Plugins are registered via [method EditorPlugin.add_translation_parser_plugin] method. To define the parsing and string extraction logic, override the [method parse_file] method in script.
+		Add the extracted strings to argument [code]msgids[/code] or [code]msgids_context_plural[/code] if context or plural is used.
+		When adding to [code]msgids_context_plural[/code], you must add the data using the format [code]["A", "B", "C"][/code], where [code]A[/code] represents the extracted string, [code]B[/code] represents the context, and [code]C[/code] represents the plural version of the extracted string. If you want to add only context but not plural, put [code]""[/code] for the plural slot. The idea is the same if you only want to add plural but not context. See the code below for concrete examples.
 		The extracted strings will be written into a POT file selected by user under "POT Generation" in "Localization" tab in "Project Settings" menu.
-		Below shows an example of a custom parser that extracts strings in a CSV file to write into a POT.

 		For example:
 		[codeblock]
-		func parse_file(path, extracted_strings):
+		func parse_file(path, msgids, msgids_context_plural):
 		    var res = ResourceLoader.load(path, "Script")

 		Rich text can contain custom text, fonts, images and some basic formatting. The label manages these as an internal tag stack. It also adapts itself to given width/heights.
 		[b]Note:[/b] Assignments to [member bbcode_text] clear the tag stack and reconstruct it from the property's contents. Any edits made to [member bbcode_text] will erase previous edits made from other manual sources such as [method append_bbcode] and the [code]push_*[/code] / [method pop] methods.
+		[b]Note:[/b] Unlike [Label], RichTextLabel doesn't have a [i]property[/i] to horizontally align text to the center. Instead, enable [member bbcode_enabled] and surround the text in a [code][center][/code] tag as follows: [code][center]Example[/center][/code]. There is currently no built-in way to vertically align text either, but this can be emulated by relying on anchors/containers and the [member fit_content_height] property.

 		[b]Note:[/b] You should not change a RigidBody2D's [code]position[/code] or [code]linear_velocity[/code] every frame or even very often. If you need to directly affect the body's state, use [method _integrate_forces], which allows you to directly access the physics state.
 		Please also keep in mind that physics bodies manage their own transform which overwrites the ones you set. So any direct or indirect transformation (including scaling of the node or its parent) will be visible in the editor only, and immediately reset at runtime.
 		If you need to override the default physics behavior or add a transformation at runtime, you can write a custom force integration. See [member custom_integrator].
+		The center of mass is always located at the node's origin without taking into account the [CollisionShape2D] centroid offsets.

 		A RigidBody3D has 4 behavior [member mode]s: Rigid, Static, Character, and Kinematic.
 		[b]Note:[/b] Don't change a RigidBody3D's position every frame or very often. Sporadic changes work fine, but physics runs at a different granularity (fixed Hz) than usual rendering (process callback) and maybe even in a separate thread, so changing this from a process loop may result in strange behavior. If you need to directly affect the body's state, use [method _integrate_forces], which allows you to directly access the physics state.

+		With Bullet physics (the default), the center of mass is the RigidBody3D center. With GodotPhysics, the center of mass is the average of the [CollisionShape3D] centers.

-		Button for touch screen devices. You can set it to be visible on all screens, or only on touch devices.
+		TouchScreenButton allows you to create on-screen buttons for touch devices. It's intended for gameplay use, such as a unit you have to touch to move.
+		This node inherits from [Node2D]. Unlike with [Control] nodes, you cannot set anchors on it. If you want to create menus or user interfaces, you may want to use [Button] nodes instead. To make button nodes react to touch events, you can enable the Emulate Mouse option in the Project Settings.
+		You can configure TouchScreenButton to be visible only on touch devices, helping you develop your game both for desktop and mobile devices.
