Ah, I found one thing that's kind of bugging me - the text tool.

It seems the text is not layer-specific. It would be nice if it was so I could have a "notes" layer that I can turn on and off for exporting two different images - one for players and one for the DM.

The text tool also seems to create text well above where I actually clicked. Ideally I would imagine the point that I click to be the top-left-most corner of the text box.

Yeah, the text tool is a bit lacking at the moment, and I think the public release still has a small bug with where the text gets placed down when clicking.

That's a really good use case for the layer specific text which I hadn't considered, thanks for bringing that up! I think the text tool is the next thing I'm going to be giving a bit of love to, it's definitely a bit quirky in how it works right now
