We hear a lot of developers like the old Component Toolbar from Delphi 7/C++Builder 6, and consider that one of reason not to move to the new release. In RAD Studio 2010 you can now use the old Component Toolbar and/or the new Tool Palette.
To activate the Component Toolbar just right click on the main toolbar and select Component. After that you can right click on the Component Toolbar to see the list of all categories available or just navigate through the tabs and chose one.
The configuration of the Tool Pallete and Component Toolbar are independent, for example you can reorder the categories, and the most cool feature is the search box for the components on the Component Toolbar.
Also, you have a new way to find components through the IDE Insight.
More to come, stay tuned.
