This would also apply to other widgets, but if you need to customize the overall appearance of the carousel slide pages, i.e.( colors, text, cards, borders, etc...) it is EXTREMELY annoying and time consuming to be forced to make the same changes over and over for each instance!

Therefore, I HIGHLY suggest adding a checkbox somewhere in the properties panel that applies your custom styles to ALL instances within the same widget. This would save so much extra production time!
