Yes, there is a lot of options here. Whenever we release something new, we release an announcement on the main page. Then, occasionnaly, it's also a good idea to scan the two forms in your account setup. Those contains most of what is available for customizing. The rest is mostly tied to each message. We also simplified a lot of things recently in order to help in that direction.
