Keeping org-id entries updated with buffer position changes

[Sebastian Wålinder]

Hello!

I often use org-id to create persistent links to headings like this:

* Foo
:PROPERTIES:
:ID:       BAR
:END:

[[BAR][Link]]

However, after inserting a line above foo, following the link BAR will take me 
to the wrong line, because the org-id database hasn't been updated with the 
headline's new position.

Running `org-id-update-id-locations` fixes this issue, but takes forever to run 
because it goes through all my org files.

How would I keep these links updated when I make frequent edits? Is there a 
function that updates the IDs in a single file only? If so, I could advice the 
open link function to run it first and update all the positions quickly before 
following the link.

Thoughts?

Thanks!
