Toby In firefox (on my end), when you create a new tag, you can't drag and drop it just yet.
You have to reload the page to make it works, if that's what you're talking about.
Another thing, more or less related.
When you try to create a new subject within a second primary tag, for example :
General 1
- General 2
In the text box, the primary tag (General 1) doesn't appear so it adds an error and you have to edit that.
I think it would be convenient to automatically add the primary tag so we can post right away.
