One feature I particularly like in this theme is the upper case SURNAMES and I would like to suggest this even becomes independent of theme and becomes a tick option in the layout or hide/show level of the Family Tree itself.
I’ve been meaning to suggest it as a request for new feature on the webtrees forum, but feel scared to stick my head out of the pram!
I will look into the config option. But doing it via css as in the simpl_grey theme is very easy. It will probably not be so easy to do it via php. Unless I can come up with something that works without re-writing half the system, it will have to remain a styling option in certain themes only. But I don’t disagree with the proposal.
