Did you ever end up with a world overcrowded with Morphs that you no longer need?  Frequently, especially when I’m prototyping, I end up with something like this:

And I wish I could delete them all at once, so I went to implement “drag to select”, just like the standard behavior in a Mac or Windows desktop.  I was finished in under a minute because I’m an amazing programmer it already exists!  To turn it on, evaluate:

WorldState easySelectingWorld: true.

To make things easier and more obvious, I’ve added a setting for this and submitted it to the Pharo inbox.

Here’s a short screencast that shows how to start digging into Pharo, and the Settings Browser:

Do you ever feel restricted by just one world?  Would you rather have an entire universe of them, with a new blank canvas whenever you want one?

There is code in the inbox that allows you to do just that.  Visually, it’s like Squeak projects.  Although, there is no UI for this initial iteration, so you create and switch worlds via a simple API:

wm := WorldManager instance.
 
"Add a world"
wm createOrSwitchToWorldNamed: 'AnotherWorld'. 
 
"Return to the default world"
wm createOrSwitchToWorldNamed: 'Pharo'.
