Window too small

[mossmann]

The default window size is annoyingly narrow. This video is a good example of the issue on macOS, and I've noticed the same on Linux: #129 (comment)

Perhaps this should be a separate issue, but part of what is annoying is that you can't see the left edge of the traffic pane contents. If the traffic pane is too small to display the full width of its contents, it seems to me that it should show the leftmost area.

That annoying behaviour can be avoided by removing the min_content_width and min_content_height calls from ui.rs.

However, doing so causes the UI to open with the traffic and device panes equally sized, which typically makes the traffic pane too narrow and the device pane too wide.

I'm not sure what the right way to customise the default split there is, such that it is set to something sensible on startup but doesn't restrict what the user does with it afterwards.
