-`po_link_to = current`: seems to work nicely
+If a given translatable `sourcepage.mdwn` links to \[[destpage]],
+`sourcepage.LL.po` also link to \[[destpage]], and the latter has the
+master page *and* all its translations listed in the backlinks. On the
+other hand, translations of `destpage` get none of these backlinks.
+What would be nice is:
+
+- if a translatable page links to another translatable page: the
+  master destpage gets a backlink to the master sourcepage, and every
+  slave destpage gets a backlink to the corresponding slave sourcepage
+- if a translatable page links to a non-translatable page: the
+  destpage gets a backlink to the master sourcepage only
+- if a non-translatable page links to a translatable page: every
+  master or slave destpage gets a backlink to the sourcepage
+- if a non-translatable page links to another non-translatable page:
+  the default behavious is nice, don't change it
+
+#### `po_link_to = current`
+
+At first glance, backlinks seem to work nicely, but a more thorough
+look is needed.

+#### `po_link_to = default`
