@franknoirot For the record I was able to take a build from https://github.com/KittyCAD/modeling-app/actions/runs/13116420540 (merge to main) and run through the flow with https://app.dev.zoo.dev on macOS

Let's list up there other things we might need before releasing it to in a versioned build.

With the fixes in #5304, we're now only waiting on nightly testing with more people to release it with #5228

[jessfraz]

other things we might want to track after that which ill let yall decide where this lives:

• button to open kcl-samples from website in the app on each sample that is single file
• update text-to-cad ui after flip outlined here: https://kittycadworkspace.slack.com/archives/C061R186RUZ/p1736007337583009

Ok so on v42 the share link command is disabled in the UI but it exists in the command bar (shouldn't be, that's a bug, but not so important considering how buried that is). Just tested on macOS, Windows, and Linux and it worked across all for me.

There is definitely a reproducible second-instance multiple second lag on opening across OSes, will file a separate bug for this. We need the requestSingleInstance lock thing we discussed on Slack some time ago with @nadr0

Edit: separate bug: #5346

[pierremtb]

@jessfraz @franknoirot both of those can live directly on the website and in text-to-cad ui, from my testing it's good to take in zoo-studio:// calls on any platform (edit: with the bug listed above to fix for best experience)

We should create issues in these repos before closing this issue.
