Is there any reason to remove BIND/UNIND operator from Morph Tool panel?
I think the usability of the panel should be kept.

Also, why is compatible_with_old_version_mmd_tools() called from save_pre instead of load_post?
Is it safe to work with old blend files without saving them after loading?

@nagadomi Thank you for your review 😃

I misunderstood the function of UILayout.operator_enum.
I will restore BIND/UNBIND operations on the menu.

It calls update_mmd_morph() at load_post and compatible_with_old_version_mmd_tools() at save_pre.
update_mmd_morph() migrates the old add-on data structure to the pull request's data structure.
And compatible_with_old_version_mmd_tools() re-migrates to the old add-on data structure.

In the future, compatible_with_old_version_mmd_tools() call will be discontinued.

@UuuNyaa I reviewed it and it looks no problem.

And I found some new similar bugs. They can be repaired at a later time.

When another collection is selected, click the Model Production Panel 's Chop button.
When another collection is selected, click the Uuunyaa Physics Panel 's mmd_uuunyaa_tools_show_cloths button.

@UuuNyaa
Thank you for the description of update_mmd_morph. I only looked at the diff summary and missed it.
