Hm I dunno if I get it right but: if you make a selection and after that select the layer, all the movements you make in this frame will be applied into all frames.
To me it’s a problem because I do a bunch of selections and move stuff in different layer in the same frame, only to find out later that all my other frames are messed up…
I can “counter” it by clicking in the cell I want to edit instead of the layer.
edit: How to disable the transformation of multiple cels?
oh I can disable it, nice
