I see you can change the colour of the heading text but is it possible to change the category colour to match. I have a dark background where white is the best colour but with the black category text it’s lost?
Hi there, @digitalPAC 
This setting is available in the Filters section on the Style tab:
Let me know if it helped or if you have any questions left 
Thanks Max, checked everything I thought, but there it is!! Out of interest where do I find a set of instructions detailing how each of these options function within a widget? The help option only suggests I contact support for any queries?
@digitalPAC Unfortunately, we don’t have a special instruction for the Photo Gallery app yet. However, if you have any specific questions, I’ll be happy to advise
