Just had it lock up my phone. Had to reboot. I've had it running throughout the day and coming back during breaks at work. Seems like a memory leak.

It was good and snappy most of the day then sort of suddenly started stuttering and froze. Couldn't force it closed. Had to reboot the phone.

Taking a look at this now, next release should have better performance when scrolling down a lot (previously I was keeping a lot in memory).
