When I've opened rose edit with this rose-suite.conf file the only "red"/error section I have is the site selection - which we did not want to default anyway, otherwise all good from the diagnostics perspective:

Happy with changes, and have independently checked the proposed rose-suite.example has the SITE 'red triangle' only now, thank you.

Will leave David to mark conversation resolved and merge when ready.

Have thoughts on other aspects of GUI layout (can discuss), but propose those sit in different issue/PR.

STOP PRESS: Please double check if SURFACE_SYNOP_OBS set True as default - should be set to False in example.

ukmo-huw-lewis thanks for the stop press, have checked and fixed accordingly - will resolve conversation and merge.
