The expand of a partition on a basic volume (expand to the end of disk, expand to rigth) is a fine thing. But we need in some cases an expand to the begin off the Basic volume (expand to left).
The possible way convert the Basic volume to a dynamic volume and then consolditate/merge first part of volume (from begin of disk to the begin of the second partition) changed the Basic volume permanent to a dynamic volume (not our favorite).

It should be possible (and simple?) expand a partition to the left side
Please do it!

Example.
