I have been doing some work this afternoon on menu buttons, as some of the existing buttons do not fit in very well with the Pak128.Britain theme. Here is what I have come up with so far, including completely new buttons for the message centre and the underground mode:

I hope that this is helpful :-)
Thanks - that's helpful. Will include in the next release.
Edit: another thing that could do with changing is the advance timeline by one year button. Maybe the world + key graphic you have included but with world and a "+1" message?
I have sent you an updated version, using the Pak128 fast forward button without the "W" (which is similar to the Pak64 "advance timeline by a year" button, but fits better with the existing pause and fast forward buttons).
There is a new feature in the nightlies and the latest version of Simutrans-Experimental that also needs a new button, however: see here (http://forum.simutrans.com/index.php?topic=2487.msg24995#msg24995) and here (http://forum.simutrans.com/index.php?topic=2506.new;topicseen#new) for details.
Edit: I have now sent you a further graphic with a suggested button for the new feature. I have been sending them by e-mail, incidentally, because I have been having trouble with files.simutrans-germany.com.
