Is there any place where I can find more documentation on Script Dragon?

I'm making my first mod and I'd really like to use script dragon. I want to know a few things before I commit to it though, and I can't find much information on it. I thought perhaps some of you more experienced folks can help me out.

1-) Are all game functions accessible through script dragon? For instance, functions that create/control quests, spells, enchantments, idle animations etc. Features which are normally not available through papyrus but are controlled through GUI on the CK.

2-) Is it possible to make script dragon access SKSE functions?

Thank you.

I don't even think ScriptDragon is supported anymore. Is it even functional with Skyrim v1.9?

With all due respect, I think ScriptDragon needs to die out. ScriptDragon indeed supports the latest version of Skyrim, but virtually nobody uses ScriptDragon anymore, and SKSE is better integrated to Papyrus script engine. SKSE also has ongoing development to add more features, while IIRC ScriptDragon's last development is only to support the latest version of Skyrim.

Not to say ScriptDragon is bad, but IIRC everything you can do with ScriptDragon, you can with SKSE, and more. Still, I'm not well versed in ScriptDragon, so maybe it can do things SKSE can't do.

You can google "ScriptDragon 1.9" to get the latest version from Alex's website.
