If I don't want to synchronize swatches and object styles, but just paragraph styles.
The problem is that when I synchronize paragraph styles, all swatches are synchronized, even colors that are only used in object styles, and unnecessary swatches are added even if I deselect the swatches and and object styles in the Synchronize Options dialog.

Ideally, only swatches used in object, paragraph, or character styles would be synchronized when synchronizing any of those styles.

I would like to avoid adding unnecessary swatches to the document that are not related to synchronizing any of those styles.
Also, I would like to prevent synchronization from occurring if the swatches option is deselected in the Synchronize Options dialog.

However, since I don't want to synchronize the swatches, it will still be synchronized even if I deselect it.
(I deselect the swatches option after selecting any or all of those styles to synchronize.)

I understand that when object, paragraph, or character styles are selected in the Synchronize Options dialog, the swatches are also be synchronized as reported in fixed issues page.

If all swatches are always synchronized even if the swatches option is deselected when synchronizing any of those styles,
the swatches option should be selected and inactive(grayed out) to prevent it from becoming deselected.

1. Only swatches used in any styles should be synchronized, not all swatches.
2. When synchronizing any styles, there should be a checkbox to synchronize or not synchronize related styles or swatches.
3. These should be applied to table and cell styles as well.
4. If the swatches option is not selected, it should not be synchronized, just like if any other style option is not selected.
