Adding to your point of not knowing what those icons mean, I also don’t know what Modifiers and Debounce mean.
I found this few days old tutorial showing a use case for Modifiers and explaining that Debounce is delay.
I still don’t know what many components and server action options mean. And if I can’t find it here, it probably won’t show up on Google either.
Some times, I find that searching for things on DMXzone helps. And for other times, I just trouble @George and @Teodor with private messages.
