My initial reaction was opposite as well, but after thinking about it, I like the idea that potentially i'm not bound to my laptop, I can access it anywhere. Clients don't have to have a specific programme to participate. It's interesting to me. :)

I'm actually working on a very similar tool which I'm hoping to launch soon, so I won't give too much away :p

In general though, one of the biggest things for me would be the ability to prototype simple interactions and animations. When you click this, this thing flips over. When you type in this input, the search results dropdown. When you click this button, a modal dialog grows into view. When you focus this input, the page scrolls to the top of the input. And so on and so forth.

These types of interactions are currently possible in tools like Framer, Quartz Composer, Marvel etc. But having it baked into the same app as the drawing tools is where it's really at imo.

OK great, thanks for your reply Grant.

Noted. Cheers Mitch.

Oh man. A wishlist!

Off the top of my head: 1. being able to show how different elements squish/pull/stretch/move around would be great. I do a lot of specs for a dev team in India and never know if I'm being understood when I describe behavior. Showing them is much easier and makes explanations easier. 2. having elements that can natively stretch. I'm not sure how this would be designed, but essentially being able to give a text box a max-width or percentage could be cool.

really, #1 would make for a killer responsive workflow. My company doesn't want me to code anything (that's what India does), so the easier I can spec/show what I've designed the better. Plus, being able to send them a link to my designs, where they can play with how it interacts, would cross any language barriers and make me less apprehensive about sending their team stuff.

That was a bit rambling, but that's the use case I've run into. Sketch/Photoshop aren't fluid like a real browser is, but then again, our company's workflow doesn't let me into the browser, so... ¯_(ツ)_/¯

I can't speak for Brian, but it seems to me that most web apps are a subscription service. My employer currently balks at SaaS and keeping assets 'in the cloud' is difficult at best.

On the other hand, I'm probably not in your target demographic of freelancers or those businesses that see value in off-premises resources.

This does look like quite a nice tool. I hope I get to try it out at some point.

Mostly tired of subscription based services. Keeping track of finances is hard enough without every software I use being subscription based. Maybe you could be unique, and offer the cloud service on a version level. Meaning I could buy in at $$$ amount, and own that version of it for life...but a new version with updates could be released that I'd have to "upgrade" too. But only if I want. Of course I realize that creates a challenge on the development side...it's just a thought.

That all said I do like what I see. But I'll probably pass unless it's either: 1. So appealing that it's worth a subscription (ugh) 2. Offered native, or a lifetime fee to own a version.

It's worth noting that it's a huge ordeal to get work to fund a subscription service as opposed to a one time fee. Others may say that's horrible, how dare they, etc. but that is the fact of many corporations that aren't big design studios / agencies.
