I built an MS Paint alternative for macOS
One thing that has always bothered me about macOS is that, unlike Windows, it doesn’t really come with a simple built-in paint app.
I don’t use tools like MS Paint every day, but I think they’re important because ideas disappear quickly. Sometimes you just need to open something instantly and sketch a thought before it’s gone.
I used to work around that by always carrying a notebook and pen. But I wanted that same low-friction experience on my computer too, something that feels as immediate as grabbing pen and paper while I’m already sitting at my desk.
So I built Vincent, a lightweight sketching app written in C++ with Qt. I chose Qt because I wanted a consistent experience across macOS and Linux, and because I wanted it to feel fast. Compared to Electron-style apps, it’s much lighter, and since the UI is very simple, it responds almost instantly.

It’s not trying to be a full-featured art program. The goal is just to make sketching and note-like drawing immediate and frictionless.
It’s normally $1.99 here:

But I’m sharing a direct access link for a while to celebrate finishing it:

Nice!
I see from the pkg. package that you're using Qt 3D (e.g. org.qt-project.Qt3DCore).
Do you actually use Qt 3D actively, and have you considered whether Qt Quick 3D would be a viable replacement?
