Why cut paste feature is not possible

There are independent liberray and they keep on adding new components.
If Ki kad arrange by package , it will be easy .
We can change pins as per components.

I’m not able to understand from your text what is your question/problem.
So following the title and ‘Footprints’ category mentioned.
In footprint editor I have opened one footprint then selected 2 pads in it and I was able to cut them and then paste them.
I am using KiCad V8.0.9.

If you can’t cut/paste than may be it is a bug in version you are using.

If you will be writing your question once more remember that KiCad nomenclature is:

  • symbols having pins are at schematic,
  • footprints having pads are at PCB.

Your ‘pins per components’ are confusing.
May be you had a problem to cut/paste pins in symbols.

Certainly version number is first information when asking about something not working.

Same here. I assume it’s a language / translation problem. Try to express yourself more clearly.
