There is a way to customise the home page, in setup program, go to Plugins page, click on Home plugin and edit the properties.
I don't have it at hand now, but it's quite ok, but some quirks, for example double negations in setup, and those sometimes even don't work...
BTW - The setup program is configuration.exe, also named configuration in the the menu of MediaPortal. This is the same program that runs when pressing F2. But everywhere else it is named "setup" - that probably needs to be changed at some time.
Once you click on Plugins in the three on the left, right click on "Home" in the Window Plugins section. Then select configuration. A Home Setup window appears. Un-check the Scroll menu items in the "Home Settings" area on the left.
