These two options would be spectacular in vMix 25

1 - Be able to integrate a matte map for transitions with stinger.
Stinger is phenomenal, but we can only use it by covering the entire screen and marking a cut-off point, it is very necessary to integrate the matte map for this transition.

2 - Being able to mount several layers in one is very useful, but the functionality is lost a bit because when wanting to put a luma key or a transition (Wipe, Zoom, etc ...), it only applies to the master layer, and the rest comes out superimposed.
This limits your making more creative compositions.

Thank you very much for your attention, if perhaps there is already a solution to any of these issues, I am very grateful to the community for the support.
