Visualisations are (still) not 'pluggable', they are integral part of the player executable, but each new version has more and more of them.
BTW, I pesonally don't have that many problems with new betas, but it would still be a good idea to become familiar with 1.03 first and finish initial loading of the player before experimenting, but then do give betas a try. They are safe (in the worst case they don't work in some aspect; they never damage the music - so far
), and it is easy do downgrade to a stable version if you change your mind.
You used 'her' for your friend - nice, we have so few ladies on this BBS (actually, none currently active, and I think a grand total of three or so).
Wellcome!
