The new stereotype dialog introduced in V14 seem to intend to address a better filtering of many stereotypes. However now setting stereotypes is more often a complex or even impossible search.
Example: In V14 in tried to change an object in an SysML activity diagram to a <<datastore>>, but I had to go to UML instead of SysML1.5 to do that. In build 1503 even in UML the <<datastore>> has gone. I have no idea how I can set my object to be a <<datastore>> in build 1503.
Please validate what is shown in the stereotype list associated to a Perspective/Profile.
Currently it is more or less useless.
