Drew a bit in the new version. Can definitely feel the speed increase!
Layer order seems be consistent each time I open a file now. So that's fixed. Some of the other layer related errors remain unfortunately. I still can't easily reorder layers on the tablet, only move the selected one to the top. Chrome still pops up a "Download, Share, Print" when I long press on the layer as well.
There's still an issue where the canvas sometimes doesn't update correctly till the next time it's forced to redraw, leaving stray pixels. This seems to happen mostly when using undo and redo. I've also seen it undo an earlier action instead of the last action I did. It's messy and kind of hard to untangle what exactly is going on. I'll continue to watch for this and see if I can figure out exactly what's going on.
Newly discovered bugs.
The layer thumbnail images seem to only show a small piece of the layer's contents, not the whole thing shrunk down, this can result in some of them being completely blank depending on what area of the canvas they happen to slice.
Animation frames have the same issue layers do when trying to move them on the tablet, except you can't move them at all (I bet it's also only registering dragging upward). They clearly highlight and do that little scaling pulse but then can't be moved after, the way they can on PC. Not a bug but that pulse feels way too long, if I was re-arranging several frames it'd be very frustrating to wait that long before moving each one.
Not bugs but general feedback.
It would be nice if that animation default frame length was something more typically used, like 0.1 seconds. 1 second is waaaay too slow for most animations.
There isn't a good way to actively preview an animation while you are drawing. It would be ideal if the navigation/preview window had a play button for this.
I find the layers having different canvas sizes a bit confusing, especially since it seems to auto crop each layer when importing a psd. I get the idea behind it for handling exports though! I think I still prefer a conventional slice tool for that, but having a layer toggle that lets you draw or move selections outside a layer's bounds and have the layer auto resize to adjust would fix my main issues with it though.
