This popup menu had become very long. You can revert to the previous behavior by using the "InlineObjectMenu" parameter. For example:

"C:\Program Files\PLSQL Developer 15 Beta\plsqldev.exe" InlineObjectMenu

You can also add the following line to the Params.ini file in the PL/SQL Developer installation directory:

InlineObjectMenu=1
