https://stackoverflow.com/questions/74045604/can-not-create-a-maven-archetype-project-the-progress-bar-get-stuck-in-33

In addition, I click show progress view button in bottom right, or Window > Show View, it doesn't appear,


after a long time I find that click restore button in the upper right corner, the welcome view become half screen to right,
and project explorer, outline, progress view show in left,

I propose let welcome view auto dock to right or embed in Project Explorer title bar when do show view action.
