I had trouble for a while when copying a value from a freeform pannel.
Let's say I have a Page dimension and i want to copy one of those values.
On PC, i did not find any other solution but selecting it with the mouse and then Control C to copy it (which by the way don't always work as it doesn't always select only the value i want but the entire line, including in my examples my visits numbers).
Discussing with colleagues, it seems i am not the only one annoyed by that matter.
So here is my idea:
What about adding to the Right Click dropdown Menu an option which would be "Copy" of "Copy Value" to make it easier ?
