Illustrator is a great program for creating illustrations and graphics. However, if you want to add more tools to your toolkit, there are a few things you can do. One way to add tools is to install the Adobe Illustrator Extension Library. This library contains a variety of tools that you can use in your illustrations and graphics. You can also find free tools on the Adobe website. Another way to add tools is to use the Edit menu in Illustrator and select Add New Tool from the list. This will open a new window where you can choose from a variety of options, including an image editor, video editor, or 3D editor. Once you have chosen an option, you will be able to create a new tool by clicking on the blue plus sign next to it and then typing in a name for the tool. You can also find these tools in the Tools palette under Miscellaneous Tools.
