Some pages in tl-setup exhibit external links to support pages. Currently, as far as I've been able to determine, these are • Welcome page • External connections • Sudo • Summary It is not evident why these pages in particular warrants this extra support. For consistency, all pages should link to some form of support.
The four listed pages are quite different, so there is no single principle why links are warranted that could apply to all. We need to come up with some guidelines how we can make sure users have the information needed, balanced with not cluttering the interface too much. I don't think it is as simple as adding a link to every page.
