It often happens to me that I want to clear the current output window by using the context menu, but instead of hitting the Clear entry, I accidently hit the Close entry (which is directly below Clear).
How can I get that output window back!?
Via Window/Output/Output I only get the container tab for all output windows. How can I reopen the output window of a currently running application?
In the right bottom edge there are information about NetBeans updates. Left to it, there's the tasks running (building, running application etc). Click on it, right click the process you want and select Show Output.
