Hi Jay,

Sorry I meant to respond to this a few days ago. Currently, in the
dashboard you have the ability to copy/paste a template into a text area
and then edit it before you attempt the stack-create. This seems to solve
the use case that you have mentioned although I agree that there is room
for improvement in the user experience.

The reason I bring up the distinction is because the template that you
reference below has a much broader scope. It includes storing and managing
templates for future use. If you are intending to add all of this
functionality into the Dashboard then I would suggest waiting for a
template storage solution to get done. There is currently a blueprint and
discussion happening in Glance to take on this ability and then I would
imagine that the Dashboard can consume it.

see:

If you are intending to simply add an additional page for editing the
template if the user chooses to retrieve it via the URL option then my
only suggestion would be to have a flag that gets stored in the session
that allows the user to bypass the editing step for launching templates
since some users will never need to edit templates.

I agree with Liz here, templates can be in JSON or YAML format so if we do
add a javascript library to provide syntax highlighting and things then I
would want it to work with YAML as well as JSON.
