I’ve had this problem for quite some time so happy to see a fix may occur. Thanks!

@julian the inherited themes didn't work before, but is it possible that now you've made this commit: https://github.com/NodeBB/nodebb-theme-lavender/commit/7f8e9e4df0f0d20e8b83ab096c1443544df9bd4c There is scope for the template inheritance to be used there instead of the hardcoded rule 'nodebb-theme-vanilla/templates'? Right now I'm maintaining an entire theme that's a fork of lavender just so I can restyle one or two pages.
