Idea : being able to hide scenes from the matrix

[Warths]

Hello and many thanks for this awesome plugin

In my experience, heavily nested scenes collections can become a nightmare to configure.
I personnaly heavily uses scenes only as sources in "displayed scenes", and have around 40 scenes for a maximum of 6/7 displayed scenes that will benefit from transitions.

So i though it would be a nice addition to be able to hide some scenes in the matrix so we can have a clean view of what's going on.

The current workaround is to order the scenes but it has its limits, as we don't necessarily want to have them in that order in the scene list

Thanks !
