I don't expect you to.
After I wrote my note above, I found David Thorpe's comment from July 2020 about the sort order of alphabetically named macros. I particularly appreciated his comment about getting up to
That's what the extra names mean to me, ways to group macros rather than simply order them.
Unfortunately, he also discovered that
which messes up my "intuitive" notions of grouping.
There are many more ideas in this thread than I found in my first skim!
Thanks.
Mine too! 
Hi @DanThomas, I encountered 2 problems with the Palette Organizer when I upgraded to macOS Monterey and KM version 10.
After upgrading to KM 10, the numerical mapping works, but when I set a separator, the separator is not displayed next to an error message.
Here a Video
After the upgrade to macOS Monterey and still under KM 9.x the separators were extended independently in all macro palettes.
Still under macOS Big Sur they were aligned to the length of the macros.
I don't know if this behavior is unique to me. Can you reproduce this on your Mac?
As far as the separators are concerned, something changed in Monterey so the separator characters aren't the same size as they used to be. So you'll just need to shorten them by hand.
As for the error message, everything still works, right? If so, for now just ignore the error.
Hey @DanThomas and @appleianer, I can confirm that on Big Sur the separators cause an error message and they are not inserted. Everything else, including the numbering works properly. But the separators are not inserted. So I have been having to copy and paste "separator macros" and numbering them manually for the time being.
Below is my system info (it occurs on my iMac too, also running Big Sur).

EDITED TO INCLUDE ERROR MESSAGE AND IMAC INFO
I get the same error as you on my MacBook. ↑
On my iMac I get the following error ↓

The UUID is different each time of course, for each separator.

Same here, separators are not inserted, here is the error message. Operating system is Big Sur, Intel MacBook Pro 16 from 2019.
Look at this image:
I believe this will solve the problem. Please let me know.
Hey Dan, that works on my iMac. I'll test it in just a bit on my MacBook in just a few and report back.
UPDATE: That solves the problem on my MacBook as well. Thanks so much Dan!
Thanks. I had to laugh - I didn't even know this menu item existed! Way easier than resorting to AppleScript. 
Hi Dan,
I'm not quite following the recent conversation.
Pardon me for the question: Do you want all of us to do the same?
I imagine you would need to do this if you run into the errors we experienced upon upgrading to Keyboard Maestro 10. The AppleScript stopped working, but can be fixed by using the menu action Dan mentioned.
Otherwise if the macro is running fine I'd leave it alone.
Great. Thanks!
I have not used it since upgrading to v10 except to call up the reordering window. I have made the same change.
@DanThomas also with me the change (green arrow) has helped and it is carried out correctly again.
Could you please tell me where in the macro I can make the setting to the length of the dividing line?
See:
Otherwise, I believe you will need to edit the HTML file.
There is no setting. It's based on the longest macro name in the list. But you can change the divider text to anything you want. When you add a divider to the list, the first character in the divider string is saved, and used the next time you run the dialog.
@DanThomas just that doesn't seem to work under macOS Monterey anymore. Here is an example with very short macro names:
After upgrading to macOS Monterey and launching KM for the first time, all my palettes had overlong separators.
I have this behavior only under macOS Monterey. Must then be a bug in macOS.
Use a different character for the separator. For some reason, these characters are wider, under Monterey. I don't have Monterey, so I can't test it.
Yours actually looks nicer.
On my end, the dashes overlap, creating dots that are visible to human eyes.
Thanks for the tip. I will give it a try.
An easy way is to do a search & replace in the Keyboard Maestro Macros.plist file. I think it should be safe to replace only the dashes string, since they are unique. However, make sure you have a backup before doing that.
