1. Make ability to create wiki documents without body
Sometimes documents hierarchy may contain documents which serves as folders for other documents.
Making document body obligatory makes the process of wiki creation slower.
For example, i want quickly to add a new wiki document "Getting started", which will be the first document in "Development for Android" folder. And later I will add more documents to this group. At that moment I don't want to spend time to make any description(body) for the "Development for Android" document. And, to be honest, I don't want to add any at all. But the engine doesn't allow me to create the documents without body, so I spend some time and put some trash text here to skip this step asap and start to create the subdocument "Getting started".
2. Make ability to create multiple documents by one click.
From the example above, if I am in the wiki root and press "New document" then put the following line into the input field "/w/Development for Android/Getting started" i would prefer to have both "Development for Android" and "Getting started" documents to be created. But in case when "Development for Android" is not exist yet I am just getting an error and should create these 2 documents one by one.
