Each Widget runs in its own system process, separate from other Widgets and the main Konfabulator system process itself, thus improving the stability of the software application as a whole. Should a problem occur with a Konfabulator Widget requiring it to be shut down, that particular Widget can be shut down without affecting other Widgets or the main Konfabulator application. A disadvantage of doing this, however, is the extra computer memory needed for each process to run. Computer users who are careful about computer memory usage or run computer memory-intensive software applications usually point this out as the main disadvantage or their main concern about Konfabulator.
