Not sure if there's still a lot of Unity refugees, a lot people seem to have settled on Gnome+dash to dock (and other extensions).

Were there? Can you point me to the complaints? Are they on a mailing list?

What about making videos a bit "bouncier"?

I am certainly open to collaborating on this. 5.11 used assets from previous videos due to being my first contribution to the KDE Promo group so I am absolutely open to suggestions and to ways for improvement. What do you have in mind?

I'd suggest taking a look at my video about making Unity on Plasma. Kubuntu team has considered doing some work on making a custom layout option for people who dont want to leave the Unity workflow. Perhaps, the work could be collaborated on with them.
