-* \*anchor creation
+* anchor creation
   * *must* be unique
-  * 10 digits, usually current date+time (YYMMDDHHmm)
+  * default: 10 digits, usually current date+time (YYMMDDHHmm)
   * but, if multiple links created within one minute (or other circumstances), this would duplicate
   * thus, duplicate-check before creating a new anchor
   * if duplicated, generate first *non*-duplicated link (recursive?)
+  * try to move *backwards* through minutes not forward
+    * i.e. if 2030101200 exists move to 2030101159, 2030101158, ...
+    * if moving backwards, we do not take away id space from *future* note creation
+    * if moving forwards, every zettel created within a minute would delay next zettel creation *another* minute
