It would be useful if WW would support user processing after installing the WW update and prior to starting WW.exe.
I keep my map.ww additions as a separate file which makes it easy to merge with the WW install version. A simple .cmd file merges my file with the WW file and it would be very convenient to have the WW update install execute that .cmd file before restarting WW.exe.
A generic approach would be to test for the presence of a .cmd file named WWpost.cmd and if found in the WW folder executed. End users could then customize such a file to fit their individual needs.
