It would be helpful if we're able to copy text from notifications as sometimes errors and warning show up there and if copying is allowed, we can easily paste it to bug reports or other places where necessary. Example: issuing a notification using eg. `notify-send "title" "body of text I wish to copy"` pops up a notification, but I cannot select nor copy the text displayed. This seems to have been resolved in plasma 4 as per bug 217606, however it seems to be an issue again.
You can right-click the notification and chose "Copy", no?
Yes, I can, from the body of the notification. I did not notice this feature until now. It is a bit unintuitive for me, as there is no other indication that you can interact with the text, but I accept it as it fullfils the main purpose of this wish.
It's a bit of an unfortunate situation, agreed. One used to be able to select text in the notification but we now implemented the "default action" (one that is triggered when just clicking the popup, as is common with most other desktop environments). Then you might also be able to scroll the notification if it is too long. We have three conflicting mouse interactions here and we didn't find a way to fulfill all of them. :/
