Although there's been progress, Tana's UX & UI is still clinging to a Windows 94 look and feel.

If you don't get a proper design team for the new Tana - as in the macOS aesthetic kind of folk - I doubt the new tool will go anywhere.
PS: would love to hear what we should expect from Tana outliner going forward. Some of us are paying yearly subscriptions.
