Explorer query functionality

Is there a way in the Explorer to associate JPQL queries with query result windows?  I would really like to be able to open multiple query / result tabbed panes and be able to save out my queries, similar to what you can do in Benthic Golden or Toad in the SQL world. Alternatively are you aware of any other JPA + JPQL workbench tools, commercial or otherwise that would support this? ... a way in the Explorer to associate JPQL queries with query result windows?  I would really like to be able to open multiple query / result tabbed panes and be able to save out my queries, similar to what you can ...

significant performance decrease

we are using objected in embedded mode (on OS X and WINDOWS). The database increased now to around 400000 entities of one class (database file size around 1.5 GByte). The response time of standard queries increased with this database size to an unacceptable rate (several seconds compared to around 30% when the number of entities was just half of the current). We tried to optimize the cache settings, current objectdb.conf is: <!-- ObjectDB Configuration --> <objectdb> ... the query still has to be executed, unless the query result cache can be used.
