There are themes with very large/high MCP layouts. If there are many windows and the mixer is open in the docker, the mixer will be cut off at the top or bottom of the docker. It would be handy if a vertrical scrollbar was then displayed to access the hidden functions in the mixer. Technically, this should be easy to implement. Just show the vertical scrollbar if the mixer window is smaller/lower than the minimum size of the MCP, which is defined in WALTER (second two coordinates in mcp.size).
This is also very useful with a large MCP and a small screen resolution, such as a laptop, tablet, etc. You also have more freedom when designing a MCP.
