There may be occassions when you would prefer to link people directly to your program in the editor without the additional step of clicking edit to get to the program.
For example, this URL https://makecode.microbit.org/_Mqt25iTbMX2s generated by sharing the MakeCode program will take you to a screen with the editor embedded underneath the title of the project and a button to edit.
By prefixing the part of the URL that has the unique ID of the project with
#pub: eg. https://makecode.microbit.org/#pub:_Mqt25iTbMX2s we can take people directly to same project inside the editor.
