Currently the most recently used list can be set from 0-8 in the options.
Via the registry, this can be increased up to 16 (anything above 16 seems to be ignored) though I find that going over 10 causes the right-click menu to scroll.
I'm always forgetting the registry key and have to hunt around for a few minutes any time I want to make a change.
Can the options be expanded?
Additionally, could it be changed so that the menus no longer scroll when they get "too long"?
I seem to recall someone mentioning that Media Center limits their height to half the vertical screen resolution.
80-90% seems like it would be more appropriate, and would help when accessing the menus using high DPI scaling values too.
I also wonder if a "Recent" sub-menu might be preferable to adding the MRU to the top of the right-click menu - at least as an option.
Or perhaps a double-wide menu, with MRU items on the left. That would fit 12 items rather than 8.
