Also when I take away the line:
<extends>minimal</extends>
The template falls back to default. How am I able to test all these brand new features. Growing frustrated.

also tried : <name>TFRminimal</name>

But no success.

as a first step, you should use the template editor to extend minimal template, to see what kind of config file it generates.
I still have to write the import script for custom templates (the XML must be imported to database, right now it's not done)

Is this something that I could have known?

If the "older" way of working: creating a template by FTP-copying a template from /templates to /upload/template does not work, they should not show up in the dialogue where you can choose a template...

I think I've already told it yep.
whatever: I finish some bug fixing, and move back to LS3.
I'll first add the template import if you want

OK, thanks. Maybe you told me, but I misunderstood.

@LouisGac: I hope you can find time for this. I would like to start fiddling and eventually developing a new template.

I also tried cpoying a template using the template manager, but after that the "new" template is unusable.
