Change font size of Message Text in the middle of the screen

Can you please add an option to change the font size of the MessageFont (subtitles, objectives, ingame-events,…), which appears in the middle of the screen. It is still designed for low 4:3 resolutions rather than modern screens.

An option to position the the message-text (player chat, as well) would be great, too.
With 16:9 resolution (and some UI scaling for the bottom menu), there is some space on the bottom left and right of the screen.
There could be maybe 7 options: top-left, middle-left (chat default), bottom-left, middle (message default), top-right, middle-right, bottom-right.
If both are selected in the same position, the text could be maybe stacked or merged into one chat-box.
