After reading a post from Erel, I realize bookmarks can easily be replicated using comments.
I switched to using comments like '##0 and '##1 for temporary bookmarks, or I will use more descriptive comments like
'##FIX - Sort Order
'##TODO - Implement Styles
for more permanent bookmarks.
Now I can do a find on "'##" to see all of my bookmarks. Or find ##TODO to get all of the todo's. (I use "##" because that won't be used elsewhere in my code)
I find this works far better than conventional bookmarks.
