Does setting the hallo theme in the application propierties still work?
Could not find it in the documentation 2.x as in 1.5
https://docs.jmix.io/1.x/jmix/1.5/ui/themes/theme_usage.html
I’ve tried setting
jmix.ui.theme.name = halo
in the application properties, but it doesn’t seem to make any effects.
