The new feature where closing an input window redirects input to the command-line caused a bunch of problems for me today.
One of my guides kept closing windows in the conferencing system, thinking he had cancelled his entry, only to have the next the he typed (".west" on several occasions) create new conferences in the system.
He did this about four times in a row.
Could we revise this so there is a minimize button and a close button? Minimize would do the current behavior, close would return a null value for the request...
The problem with this idea is that not all prompts can accept a null value, so this could be just as confusing. This logic was the reason that initially there was no close button at all.
How about this compromise? The close button can parse whatever is currently entered into the popup (null if nothing). If this is invalid, then the system can reprompt, this time on the command line.
