FYI I put an optimization in place in the next update for large displays that hopefully will help. I also realized I was double-updating note stats due to the feed refresh, so that's fixed in the next update too. With 9 columns the note stats will now update 1/6th as often as they were before (rather than updating all those note stats twice every 5 seconds it will only update them once every 15 seconds), which hopefully will save your CPU!
