It's kind of legacy stuff from before I had cropping hooked up. You blew up Verve, because you went beyond your graphics card memory...
The transparency thing is a trade-off for having the fluids and paint work they way they do. Know it and understand how to work with it and all will be well. Consider it a quirk of the medium. It's ok, while you sketch in one color on one layer, but if you really want to paint, you should consider filling the canvas as if using a primer with real oil paint or acrylics.
As for [n] going through random colors, I wrote about it in the docs. If your currently active swatch list has only 1 swatch, it will use random colors. Only if your active swatch list has more than one swatch...yadda yadda...you see? If you have more than one color in your swatch list and [n] brings up random colors, please, let me know and show it to me in a video!
As for cropping and wicked stuff happening...ahaha...

...I somehow must've not expected anyone to do what you do.

...
If you drive with your car at 180 km/h and you yank the steering wheel all the way to the left, you may fly off the road with a deadly accident! I recommend you never driving a car!

...the only advantage of that situation is, you won't be able to report that bug to the car company.

But, kidding aside, there are many things that need improvements and fool-proofing and all that. Just because we're on a computer where a program could be developed for that serves all our digital dreams and wishes, doesn't mean we can expect that from every app (or any for that matter), (let alone a free one

)
I get you, though, really. And I value your feedback! I'm so used to people accepting the shortcomings of Verve as it develops for the things it actually does well. It's interesting to get a reaction of someone, who is, ehm... like you!

As for photoshop vs. Verve...they're very different tools and though I try to have some of those "conventions" regarded, I still want to fine tune others to my liking or the logic I see more efficient. Photoshop comes from a very old technology and is stuck in less fortunate paradigms here and there. I have no interest in inheriting those for no reason. But I also see the dilemma of habits. Especially while Verve is still in its infancy.
Again, thanks for your feedback and I'll do my best to find a healthier balance between habits and accidents, haha.

(By the way, I thought about square constraint very early on and totally forgot about it until I started with the brush images, which actually has something like it, but the whole selector square handling is even worse than for cropping, hahaha, so...please, don't try too much stuff with that! Everyone else: go ahead, it's weird, but fun!
