Sure, but this also has an easy solution - don't morph, have an inactive menu in place (with an indicator of wort work in progress) that activates when the work is done
Thank you. There are sane, good ways to build UIs, and after 30 years of programming, my main complaint hasn't changed: "Stop doing what you're doing, and do what I want."
Be like TRON, fight for the user. Not the developer. Not the developer's politics or opinions, and certainly not for the computer itself. The user's wants are the #1 priority in a human-computer interaction.
