It's frustrating to have to be in the Host account to pass settings to forms and templates. Also, it's a hassle having to remember what the settings are...
Putting that together, it'd be nice if I could, somewhere in forms and templates, define module variables. Then, those would show to any user who can set the form and template. Depending on the form/template choices in the "Configure" window, the variables would be shown that are defined in the template and let the user fill them in.
For example, as the host, I could make a template with a defined variable for "TargetUserID" and then, when an admin adds xmod to a page, goes to "Configure", and chooses my template, they'd see an entry somewhere for "TargetUserID" that they could fill in.
From there, I could use that just like a normal module variable in the template.
