Reading this long after it was posted, I came across your comment here @whatitsworth. I am quite new and I was also wondering why it wasn't possible to save a post in SteemIt, e.g. building a "Favorites" list ...
By now, you have likely already figured this out, but there are a number of interfaces to the Steem blockchain. The one I use for saving a post, like this one, is Busy.org. It is a very good alternative to SteemIt.
Not only can you save a list of "favorite" posts, but it also automatically stores a draft copy of any posts you are writing yourself. These drafts are saved until you either click on "Submit" or delete it. I don't know which of these two features I like best, but they have both quickly become indispensable to me.
That said, I do still find it helpful to go into SteemIt a lot. In fact, in my Update: Month 1 post, I cover the 3rd interface to the Steem blockchain I also find indispensable - Partiko. To learn more about it and stay on top of developments, I'd recommend you follow @Partiko.
It is a very nice (and fast!) mobile app I use on my Android smartphone. This app didn't even exist, at the time this post was written ...
While maybe too late to be of value to you @whatitsworth, perhaps someone else, like me reading this much more recently, will find my response to you to be of some value.
All the best to you!

Following you @roleerob, I noticed this comment and have just come here and read through this post myself.
Excellent content all around!
