Make the cppcheck output window visible on running check
If the cppcheck output windows is not the selected Output window, you get no visual confirmation that the cppcheck command has been actioned. If the Output window is visible you should select the relevant cppcheck window. I'm not sure if the standard practice in VS is to make the Output window visible if there is output from a command... yes it appears it is, so you should also do this.
I'm not sure it will never be annoying. We can make it an option available through settings.
I think I'm not going to do this, since we now have a tool window. But the tool window must have some indicator of whether the process is still running or has finished. Ideally - a progress bar (which is not impossible with cppcheck).
Just to make it clear: now this task is "Make tool window display some notification when check is started/finished".
On a related note I find it annoying that it switches me to the cppcheck output window so frequently. Perhaps an option to never switch to the output window and/or an option to only switch to the window when the check is complete and there is output.
I have visual studio set to switch to the output window on compile so it will switch to that then if a message comes up in cppcheck it will switch to cppcheck output, then I'll switch back to output because maybe there was a compile error. Then while trying to read the error more cppcheck output will come through and switch me back to that window and so on.
