Is your feature request related to a problem? Please describe.
The current available condition "Points in talent" doesn't provide the best opitions for setting up opacity for icons, as you u have to set opacity for "Failed condition" in order for the icon to show/hide and then you can't decide properly different opacities for different situations (ready, not ready, out of range, out of resource, etc). Notifications doesn't allow setting the opacity of the icon itself so you can't overover come this issue. Coming into Dragonflight with the new tree system I think this would make an awesome feature to be implemented as you change builds and talents faily offen in different contents.

Describe the solution you'd like
I would like to be able to set if an icon is shown or hidden (true/false) based in the "learned spell" condition in order to be able to set opacity settings in different conditions.

Describe alternatives you've considered
Maybe if notifications could change opacity settings of an icons? But I guess the implementation of the "learned spell" condition would make a much better and easier implementation to set up when considering setting this for a lot of icons.
