When starting Magento development, first thing you find out that in order to see the changes you have to clear the cache. There is also an option to disable the cache completely, but performance wise – it’s not a very smart move. As your experience on the system grows you are getting to know which exact cache to clear to see the changes, be it config, layout, FPC cache or any other. Nevertheless, these operations are pretty cumbersome as admin session times out from time to time. You may also know that enabling template hints is not a quick operation either.
