+1

Perhaps one should be able to define the sets and aliases and that a
set does not only include one axis, so that an alias such as
"top-left-down" are possible.

Thinking further, is it likely for different apps to want to use
different resolutions so for example mokomaze will want pretty high
resolution but another app that starts up may request/ inject (my
term) an additional set/alias to be reported.
