@digimickey Hey. I understand your requirement, and I don’t think it is a bad idea, I’ll gladly make the suggestion to implement an x-sheet panel so we can have a proper discussion with the developers about this. I’ll post the link back once I’ve been able to do this.
However we have to bear in mind that despite being the original way animation masters timed their work, this was so they could provide clear instructions to the camera man. However the digital era has almost erased the need for a camera middle man since it’s been thought of democratizing the animation capabilities of independent animators and small animation teams
More and more animation and compositing programs have brought forth the concept of the timeline, which in reality could be seen as a “rotated” or “tumbled” x-sheet. Layers are akin to levels, and frames are akin to the camera
Many modern professionals have accustomed themselves to using a timeline, and even programs like TVPaint which is all about “tradigital” animation, fashions this but they compensate by having the alternative X-sheet window for veteran animators.
It might take time for this feature to be available, or even implemented into Pencil2D. If you must have it, I suggest trying out OpenToonz which is geared for a more professional environment in traditional animation.
