Initial creation of stencils isn't very user-friendly
The popup you get when creating a stencil is a bit frustrating, particularly not having a sample rendering, as you do most elsewhere.
As a result I've realised the best thing to do is quickly create a stencil and then edit it in-page, as it's a much better editing experience.
Maybe adding a stencil could be done in-page, in the same way?
I want to get rid of all modal windows (i.e. popups), actually. Making the new creating form similar to how editing works is a very interesting idea, I'll try it.
PS: BTW, is there anything especially frustrating about stencils form, compared to new quest form? I thought they both share the same issues.
When creating a quest I'm generally only wanting to write a short paragraph in the description, but for a stencil it's generally more involved.
