Menu > Tools > Pan tool
Menu > Pan Tool -- next to the "Zoom-1to1"
When you say ALL tools do you mean all tools that are in Pro Studio?
No, just Paint Studio.
Generally speaking, I don't think it is necessary to add tools in a Paint Studio.
However, I find it necessary to add the equivalent of "quick commands".
See Point 4...
The Quick Command panel will be added in version 2.0. It will be the same as what is available in Pro Studio but with a smaller selection of commands to match what is available in Paint Studio.
