Key frames in premier rush

I know this has probably been requested multiple times but with CapCut and their new TOS update situation going on right now and everyone scurrying to find a new editing software, I believe that key frames would be really useful if available. For example, take the Gacha Creators who animate and depend on key frames, when they want to seemlesly animate with out using another more confusing animation software, they could invest in your app and use it just as easily as with CapCut.
