I think you took a different meaning (although your post is very helpful). My 
usage is as follows: 

Suppose I've begun reading a lengthy file in a buffer. I bookmark my place to 
return later: my bookmark is on line 100. Later, I visit the bookmark and 
resume at line 100. I read for a while and now want to bookmark my place at 
line 500. With vanilla bookmarks, I would just use `C-x r m`, hit "enter" to 
use the suggestion (current bookmark), and next time I'll resume at line 500.  

As per your suggestion I've tested out methods in BM+. However, simply 
resetting (`C-x r m`) DOES lose any tag information, while the 
name-and-location commands not only force me through extra menus, but seem 
geared for changes of hard drive location, not line/point location. 

Is there a simple way to update a bookmark's point location in Bookmark+?
