Desktop laggnig behind iOS version – ThinkSpace: Next-gen Mind Map Review

I have been using the iOS version of Thinkspace on my iPad for a while and love it. It fills the mind-mapping app niche in a way that no other app does, so I was pleasantly suprised to see the macOS version in the App Store. The macOS 1.0.0 version seems to be a direct port of the iOS app, and the differences in the desktop versus mobile UIs are apparent. For example, zooming in and out on iOS is a simple pinch gesture that relies on the iOS touch interface. I have not found a way to zoom on the macOS version, since I do not have a multi-touch HID device such as a trackpad on my iMac. I hope to see a mouse/keyboard/menu-based way to zoom in the next update.
