The content of Conversations pane should take the whole pane width
On a BIG screen, there are HUGE margins on left and right of the content. When we resize the Microsoft Teams window for a smaller size, the content ajusts itself the same way Bootstrap would do. Now if we are in a BIG scree, after a while it stops enlarging and we are with HUGE margins on left and right of the conversation. It would be intelligent to either have a setting for these margin or make it ajustable all the time.

The Conversation Pane in Microsoft Lists should have option to display it also in horizontal manner, not only in vertical manner.

UI feels clunky, should have the flexibility to allow window resizing.

Classic example of ignoring locus of control. If the user has selected a large window, it's because they want to see more information.
If the UI explicitly refuses to do that, then this makes users feel less in control and that the program is actively working against their wishes.
