Feature: jlab --wait and --no-wait

[ntessore]

It would be great if jlab supported something like --wait and --no-wait options that control whether the process returns to the shell once the GUI has launched.

% jlab --no-wait
% # returns after GUI window opens

Thank you for opening this issue @ntessore! I will tag this as an enhancement, we welcome any contributions!

@ntessore just a quick follow-up, would provide a bit more context about the applications you might currently use which support the --wait and --no-wait options?

I am thinking primarily of the behaviour of GUI text editors. To behave as jlab currently does (launching and only returning to the command line prompt once the window closes), most text editors need a switch. For example:

• VS Code: code --wait
• TextMate: mate -w
• MacVim: mvim -f (for 'foreground')

For these, launching the GUI and returning to the prompt is the default behaviour. I would prefer the same behaviour for jlab, but I can see that there may be backward compatibility concerns here.
