Ask him to add the BBS widget to his homescreen
The BBS dev even has it in his FAQ that it's an issue with CM12-based Roms. Says he can't reproduce it and the CM team will have to fix it. I asked in the CM12 thread you linked and in the Resurrection thread and got confirmation from other users having the same issue, even on the latest build
I even tried that new Layer app on the GPE Rom because I'm so desperate to get rid of all the yucky white, but either it's not working right yet or the Rom would need to be modified to properly use Layers.
Just a matter of time though, I'm sure my previous KK Rom (Carbon) will come out with LP eventually ... or another good one that does what I expect it to
