It is tedious to go through them (and not like one after the other)
even more TEDIOUS: checking/comparing mouse cursor iconsets
In case I haven't previously suggested this for Refracta:
ship the distro with root's home populated with a config specifying a different mouse cursor set, different DE theme/wallpaper
different from the config provided etc/skel for non-root user accounts.
My peeve with "bloaty" icon themes is that they (the theme creators) oh-so-creatively presume to redefine/undermine
the intent (and or "brand recognition") of each program author.
As an invented example, What is served (other than iconset creator ego stroking) by taking away spaceFM's "shiny cube" icon
and replacing it with a friggin "looks sorta like a parrot, with palm trees as legs, smoking a joint" icon?!?
