Maxwell Cloud: a new button was added to force-stop the cloud render by killing the cloud machine (if the render has already stored any file to the server, it will be kept); this gives the user a tool to immediately stop consuming cloud time.
Maxwell Cloud: a new button was added that allows the user to easily copy the render IDs in case they need to report issues with a render in the cloud to the Support team.
Maxwell Cloud: the job wizard fills the Render Options panel from the MXS data. In case there is more than one MXS to be rendered, it will use the first one of the list.
Maxwell Cloud: message text improved on file overwrite when the user downloads the render results.
