Ctrl-N should open a new window

[blackears]

I'm just trying out BeeRef for the first time. While I am liking it so far, I've discovered that Ctrl-N has the side effect of destorying your entire tableau. I was trying to paste an image and meant to press Ctrl-V, but because I could not see the keyboard clearly (I had my glasses off) I accidentally pressed Ctrl-N. This resulted in all the other images I had pasted immediately disappearing with no way to undo it.

Since Ctrl-N is meant to create a new scene, I think it would be better for it to create a second window or at least present some sort of warning before clearing all your data. Right now it's an easy way to accidentally delete all your work.

I'm using this on Windows.
