Late last night and today I've been doing a lot of testing of the scheduler.
As expected, there were a lot of bugs in the initial version, but I fixed a TON of them last night, and some more this morning.
As far as I can tell, everything seems to be working flawlessly on Android 4.1.2. I haven't tested other OS versions yet, but over the next couple days I will start testing on 2.3.
As of now, I expect to release the new version on Monday or Tuesday.
