I often find myself in a place where I load an old project with an already configured (old) kit. When I then want to switch the kit to a newer Qt version, I have to enable a second kit with the new Qt version, configure it, right click the previous kit to disable it.
The last step switches the kit automatically to the selected, which can take substantial time for big projects. Then I switch back to the new kit, which again takes some time to configure.
If I do this too quick, Creator sometimes even hangs or crashes.
It would be great if right-clicking a kit in the "Project" view wouldn't immediately switch to it, so it can be disabled or copied without reconfiguring the project.
