• Change URL paths for feature, moving files around
• Move index to a controller under /schools and ensure only school users can access
• Add Manage My School link
• Add Manage Group link
• Revise school page to indicate if feature isn't available
• Revise school page to include more instructions
• Add School group index page with instructions
• Provide option to download links for whole school group

If you cut and paste the displayed link, it doesn't work. Took me a while to work out it is because digital_signage has an underscore in it and not a hyphen as per the actual route.

Which made me think about the other generated urls. Should they all consistently use hyphens rather than a mix of underscores and hyphens? i.e. currently you have:/pupils/schools/marksbury-c-of-e-primary-school/digital-signage/electricity/charts/out_of_hours. Should it be /pupils/schools/marksbury-c-of-e-primary-school/digital-signage/electricity/charts/out-of-hours

Looks good - a couple of questions, main one about the url structure.

Thanks for review @urbanwide , have added translations, removed index method, fixed the in-page link, and tweaked the URL structure. Agree it was inconsistent and likely to cause confusion!

Did you want to look again before I merge?

Looks good 👍🏻
