I like the background prayer load feature also.   The reason it was disabled is TheSnat had a couple instances of a 5+ minute loading time, and I got very nervous that we had a race condition so I disabled it.  You have to realize the feature is not just for prayers but also for PODC data, so its critical the wallet has it all in order before the chain finishes syncing...  So we will have to revisit this again and ensure there is really no race.  There is a pull we need from thesnat for the transaction list which confuses the issue (as the extra-long load started at the same time we added tx list filtering And background prayers), so we need to insert one fix at a time and verify it.
