Thank you. Your "Creating a simple extension" tutorial was very helpful. I presumed an extension could modify the menus and avoid the need to use Tools → Customize, but I wanted to keep it simple as a learning project, at least for now, and what I have also serves my needs quite well.
After writing Favorites, I discovered
hanya's
Bookmarks Menu extension which offers many more features. But Favorites is 13K with 5 Basic macros and 1 dialog while BookMarks Menu is 1M with 16 Basic macros, 29 dialogs, 45 Python scripts, 8 help panels, 68 icons, and a whole lot of other stuff. I'm sure it would take several weeks to study all of that programming. And I wasn't able to determine how to actually create any bookmarks — I can't add anything to the Bookmarks menu — though I did not want to spend much time reading the help panels since I don't plan to use that extension.
