Below are the other iterative updates we plan to make to improve the App Layout.

Move Channel Info and Menu to the Right Sidebar

The plan here is to utilize the Right Sidebar to display more Channel Info and Actions. The Center Channel Panel will collapse to reveal the Info RHS Panel below.

Add the Info Icon to the Channel Header

This icon will give access to open the channel info in the RHS.

Move Channel Members Popover to RHS

This will be a subpanel to the main Info panel

Pinned Messages become a subpanel of the Info RHS

Pinned Messages will stay in the RHS, but will become a subpanel of the Info panel. It will still be accessible from the Channel Header Pin Icon Button.
