Scratch

I think that hiding the stop button is likely to result in lots of problems for new users.
Why do you want to hide it?  Just to frustrate people who want to get out?

Just commenting that an idea is good or "not very good" is not particularly helpful.  Instead, writers on the forum should try to explain what they like or dislike about an idea---what *makes* it good or not so good.  This sort of discussion sometimes leads to modifying an idea to make it better, or replacing it with a better thought.  Just saying "yes" or "no" doesn't really help improve ideas.

I thought that hiding the stop button would make it difficult for new users to stop their scripts (perhaps for other users as well, depending how easy it was to get the stop function to work in presentation mode when a buggy script got stuck in a forever loop).
Now Technic20 can think about that specific criticism, and come up with an improved version of the idea, or decided that this unanticipated problem is big enough that the idea is not worth pursuing. 

I also asked why Technic20 wanted to hide the stop button---I didn't see a use for that, but maybe I'm missing what Technic20 had in mind.  Perhaps there is a way to accomplish what Technic20 wants without the problems that I foresee.

As for the multiplayer games, a lot of people have requested that capability in the past, and I believe that the Scratch team *are* working on it.

I think Technic wants to hide them so he/she would have more screen space.

The screen space of 480x360 would not be changed by hiding the stop and start buttons.

Maybe There Should Be A Feature Where You Can Change The Screen Size.
