Hey, nice to hear from you again! In my WIP you can, but I think the old online version didn't have it. It also was only 16bit internally, just a first test. My WIP is 32bit just like Verve along with 16bit export of PNG and drag'n'drop import. However, only last year I discovered web-workers, which is something I'll use for the proper Vervette release. This will allow mouse and UI interactions to be fast and fluent, regardless as to what happens on the canvas. I just didn't get to it, yet.
Hmmm, I do believe at least I went for desktop size for the canvas size in the old version. Ah, anyway, I'm happy you're asking. I never checked if anyone was still experimenting with it.

If you ever had any doodles with it, feel free to drop some here, too!
No doubt I'll make a proper announcement, once I have a new release ready.
Woops, not only that, the old one didn't even have pen support, hoho, dang it. Now it's got full support of pressure and tilts...
