List of issues#2482 Preserve Tweens when opening SWF files or converting them to FLA

Currently, when opening a .swf file with the decompiler, Tween animations are converted
into frame-by-frame animations, which results in the loss of the original tween structure.
It would be useful to have an option to preserve Tweens during the conversion to .fla,
maintaining the animation's fidelity and making editing easier.
Perhaps this could be a toggle in the editor, allowing users to choose between converting
to frame-by-frame or keeping the original Tweens. I'm not sure how complex this would be
to implement, but it would be a great quality-of-life improvement for the decompiler.
We already tried tween detection in the past but it was mostly not working.
There are many kinds of tweens, also many easing types.
The detection can work only for very basic tweens like moving sprite 50 pixel to the
right.
In the SWF file format, there is placement matrix stored in each individual frame,
that's why it's decompiled to FLA in this way.
I don't give this feature many chances...
