I started out fine with the update -- not thrilled about the Synth Rack being hidden away on launch, and a bit irritated that it doesn't remember where it is supposed to be when I open a saved project -- but that aside, it seemed fine.
However, over the past day or two I've noticed a sudden increase in the number of crashes. Sonar shuts down without warning and vanishes every now and then. No error message, just poof! its gone, and I have re-launch it. Sonar will have no memory of the previous project I was working on, and I have to open it from the Files menu. It's also really irritating that Sonar doesn't remember my preferred workflow setup. Every time I re-launch Sonar (either after a crash, or when re-opening a saved project) all my windows and views get crowded together on the same screen, and I have to break out my various windows to their original position. Also, things like the Navigation view (which I have never used) now appears on launch or recovery, and the Time Ruler will have various formats showing (usually MBT and HMSF). I prefer only MBT showing on the ruler. These are all minor things, I suppose, but I have to be honest and say that when piled all together they get a bit irritating.
I'm admittedly a bit finicky, and I like things a certain way, and right now Sonar just won't remember where all my stuff goes. Having to re-build my workspace every time Sonar crashes is not nearly as fun as it sounds. I'm planning on rolling back to the previous build and seeing if this patch gets any updates or adjustments. At the moment, 2016.11 is just not working for me.
