Garden Box: An Owner's Manual (Current as of 1.0)

This visual guide will help you understand exactly what the garden box is, how to use it, and how to get the most out of it. You are welcome to post any questions you have in this thread as well (but please direct bug reports and feature requests to the appropriate forum)
Anyway, let's get started!
Overview
The Garden Box was created with one major purpose in mind: to make the process of customizing your DS world, whether ecologically or aesthetically, as easy and painless as possible.
The first thing to note about the Garden Box is that it is, in fact, an agent injector, meaning it is an agent that searches your My Agents folder for compatible agents and displays them. It does not inject the same agents as your standard agent injector (it uses the DSGB chunk type rather than DSAG or AGNT), rather, it only reads agents that have been specifically written for the Garden Box. However, there are a few other things that sent it apart from your standard agent injector.
For one, it is not confined to a certain room. The Garden Box floats with your screen, and can be toggled on and off via a button in your bottom left corner for easy access. You can choose where exactly your agents are injected by use of a floating crosshair on your screen. Garden Box agents are also grouped into categories such as Plants, Aquatic Animal, Decorations, and Tools. They can be filtered according to these categories, allowing you to find the agent you are looking for more easily.
The Garden Box also supports two special categories of agents: Patch Plants and Decorations, which we'll get to later.
Anatomy of a Garden Box
The first thing to be aware of is your best friend, the crosshair:

Whenever the Garden Box is open, this crosshair will appear. You can pick it up and move it, but it will float with you on the screen. Should you lose track of it, hiding and showing the Garden Box will reposition the crosshair in the center of the screen.
This crosshair controls where your GB agents will appear when you inject them. Clicking on the crosshair will attempt to inject the currently selected agent to its' currently position. If the crosshair is in an invalid spot, say, outside of the room system, or in a space too small for the agent to inject, injection will fail.
Note the diagram below!

A: Show/Hide: This little box depicting a carrot and an apple floats in the bottom corner of your screen, and can be clicked to show or hide the garden box. If you don't like the button there and want to move it, you can double-right-click it to pick it up. The garden box will still appear at the bottom of your screen, regardless of where you move the button. Note that once the button has been moved, it will no longer respond to window resizes. If you somehow lose the button, reinjecting the garden box (without removing) will restore it to its original position.
B: Inject: This little green button rests in the top left corner of the Garden Box, and will inject the currently selected agent. If the agent is a standard one, it will appear at the crosshair, assuming it is in a valid place. Clicking the crosshair will also inject the currently selected agent.
C. Remove: The red button in the bottom left corner of the Garden Box will remove the currently selected agent. Since this means removing all of that particular agent, it is required that you hold down the Shift key while clicking to complete the removal. This is meant to prevent accidental clicking and removal of something you really didn't want to remove! However, if you wish to disable the shift+clicking requirement, you may do so in the options menu.
D. Currently Selected Agent: Clicking an agent will select it; it will then be denoted by a white border. Here, we have some cute butterflies.
E. Previous Page: Clicking the arrow on the left edge of the Garden Box will show previous agents in the list, if there are any.
F. Next Page: Clicking the arrow on the right edge of the Garden Box will show the next agents in the list, if there are any.
G. Filter: The blue button in the top right corner of the Box will allow you to cycle through the different categories of agents, allowing you to view only agents of a certain category.
H. Options: The yellow button in the bottom left corner will bring up the options panel. Currently there is a whole one option available-- that is the option to switch the shift+click removal requirement on or off.
I. Agent Information: This top line of text displays information about the currently selected agent including its name, author, and category.
J: Agent Description: This bottom line of text displays the description of the currently selected agent. If you click the filter button, it will switch to displaying the current filter category. Injection error messages, when they occur, will also appear here. If there is too much text to fit in the box, it will scroll to the next line after a few seconds.
Now that you've got the basics down, let's look at the special categories in the Garden Box and what they're capable of.
Anyway, let's get started!
