We can use the DecSoft App Builder Icons Picker dialog in several parts of the IDE. For example, to assign the icon of certain properties of various controls, to get the right icon CSS class to be used in the JavaScript editor, to get the complete icon HTML markup to be used in the HTML editor, etc.
The Icon Picker dialog allows us to use any of the available icons in the free package of the latest Font Awesome icons. You can search for icons in using a natural language (not only search by the icon CSS class name, but, considering all the search labels established by Font Awesome per every icon), determine the size of the icons, the optional animation and the optional rotation. Just select the icon that you want to use and press on it: the dialog is automatically closed then and the right icon in the right place will be ready to use.
