Sometimes, some expert shares some solution or when trying some of the examples, it turns out that we are missing some additional libraries that were not mentioned.
Although the IDE shows the warning message when opening the project, it disappears when you move the mouse out of it.
For those of us who don't have such a good memory, this implies either taking a screen shot or writing the name of each of the missing libraries and then searching for them in the forum.
Perhaps it would be useful to have somewhere in the Library Manager a list of these missing libraries.
Thank you!
