Any time I am creating a website using the Genesis Framework, I always have at least one additional website open: Chris's Genesis Visual Hook Guide. This has proven priceless for me as I create websites and troubleshoot mine as well as others. Since many of us are visually inclined, this makes the many hooks, filters, & markup visible in a semi-static way.
Another tool that has recently appeared is Rafal Tomal's Genesis Hooks Tool. Rafal has the user drop the file in the Child Theme folder and call it via functions.php, and the file shows where all the hooks are in your Child Theme. Sometimes Child Theme home pages don't contain all the hooks and this can be quite frustrating when trying to place something on the home page via hooks. However, Rafal's tool easily identifies the hooks that are in play and displays them on the screen!
Check out both of these helps. Please let me know if you know of any other helps for Genesis Development!
