 ** Doesn't always update selected tab when you select a new entity
 ** Doesn't update selected tab when you change the relations on an entity
-** Direct click-to-edit of relation role should actually work
-** Double-clicking a relation to edit it comes up with the POIs!
+* Double-clicking a relation to edit it sometimes comes up with the POIs (how to reproduce?)
 * Dynamic reloading of stylesheet/map_features, so that you don't need to reload the full page when editing them
 * If a select name is too long then, the select menu seems to give a horizontal scrollbar instead of the name of the item e.g. cuisine#Coffee Shop
 * If you have both inputSets names and buildingAddress, and name= key is filled in then the basic tab will get both, surely only name should be shown and building name should be ignored e.g. cafes. [Actually this was an issue of addr: being missing from one of them, however this may still be a problem for other overlapping inputSets]
