-* params dialog needs to dynamically update for all params
- * will not update for non-enum params
- * needs to account for added or removed params
- * example with grid params need update after notebook change
-* use .strip() on the hide property so we can do away with #slurp(s) in the templates
+* the block's import data does not handle variable params
+ * call rewrite after load, if new params appear, try load again...
