I propose to remove the Lists Sidebar group and integrate it back to the Paragraph group like it is in writer.
In impress/draw there is a separate group with no benefit in addition that it's not consistent through all apps, the List group sometimes isn't arranged well like you see in the attachment where Lists is not after Paragraph it's after Area.

draw rectangular list section missing
as you can see in the screenshot, the list group is missing but should be available. If there is only one paragraph group, than it's no issue.

chart Type sidebar layout
How the layout should look like with 3 sections in one group, I recommend the layout in Chafrt Type Group Elements with the bold headers for each section.
