Wouln't it be a useful feature to display the default value of an exposed parameter in the properties panel?
As shown in the image below with the green number - so the default value is visible immediately without need to dig into it to find the currently set value.
Just an idea, maybe I'm completely wrong, as I'm a total beginner, but I learn by looking at examples and some have so many exposed values and it is annoying not to have a simple view at values immediately.
Even further: along with an option to copy the value to clipboard, this could be very useful when removing exposure from a value with the Reset button. Reset could then grab the information from clipboard and fill in that value to the non exposed node parameter value.
I'm aware, that for a simple float this is easy, but just as an idea, I'm sure, there must be ways to do this with color values etc.. as well.
