I found reference to this idea on reddit from ten months ago (https://www.reddit.com/r/kustom/comments/453e9f/help_kwgt_set_more_than_3_alternative_locations/) but can't find it here - trying to use several weather forecasts but unable to go past locations defined in settings - custom timezone per layer would be fantastic! It feels limited in scope with only the three options for location, which seems out of character with the variability of the rest of the app..
Custom TimeZone per layer will be available in 3.26
Fantastic!
