Taken from comment on PR for testing connect actions: https://github.com/nicholas-maltbie/PropHunt/pull/132#discussion_r524586769

Need to work on improving interface for connecting. Should include the following features

• Response for invalid parsing
• Feedback for time spent attempting to connect
• Prevent multiple connect requests
• Save most recently used IP/game code when attempting to connect
• Animations/Panels/Forms for feedback on what is happening (instead of just a error in the console log for now).
