I have many Injectors connected to my AppLoader. Whenever I try to find specific ones to select in order to start rUsers on them, the list gets refreshed and I lose the position before selecting it. I have to scroll down again to find it and select it.
Beginning from version 8.4.0.9, AppLoader allows you to stop and resume the Injectors list refresh functionality.
Simply click on pause to stop the refresh list whenever you are trying to find specific Injectors to select. After you are done, you can click to resume it.
