I use Component Templates a lot. I find it to be the easiest way to start writing a test case when trying to isolate a bug. For example, one template that I have used since the invention of templates is to have a DataSource, ClientDataset, DatasetProvider, SQLQuery, SQLConnection, and DBGrid all hooked up and ready to go. When I see something I need to check out, I just drop the TDBXTemplate onto my form and I'm off and running. Unfortunately, a bug in Delphi 2005 prevents multiple components from being selected simultaneously, which means you can't create Component Templates like this.

What I've done for now is to go to the design view of the form, select the text of all the components, and add it to the Code Snippets window (select text, press Alt, and drag the text block to the Tool Palette). This means that when I want to create this "template", I have to go to the text view of the form and use the Code Snippet. I'm not thrilled about having to do this, but at least it's a workaround for now.
