suggestion for the Badlion Client Launcher

Dear Badlion team, I have a suggestion for improving the Badlion client. Sometimes when I want to start my Minecraft over the client I have the problem that I have selected the wrong version of the game. So I have to close and reopen the window to change the version. You could therefore add a cancel button to cancel the startup process. Best wishes for your Badlion Client! Lutschin
