@Jingyi-Wen Did we finalize where the refresh button should be, e.g on expander or inside? Or let me put it this way, is the current way shown by @reddyashish fine to proceed for now :)

@QilongTang @Jingyi-Wen As I am using the same expander styling used in preferences panel, I had left the refresh button where it was before for now. It might get little tricky to place it inside the expander but if you think that would be better, I can look into some solution.

Cool, I dont have a preference for this one.

I was a little bit hesitant about the same thing. I think this current location looks good. Let's not risk messing up with the expanding behavior then
