Is Electron a temporary thing until Apple improves SwiftUI on macOS?

This is not in any way the best experience ever. It can’t be unless the Mac app looks and feels like a real Mac app. To say nothing of its resources hogging for what should be a small background app.

In 1Password 8, you can't move the preferences window around — that is not how Mac software is supposed to work.

In 1Password 8, the close button for the preferences window is on the right — that is now how Mac software is supposed to work.

In 1Password 8, the menubar, which should be the hub from which you can do anything you need to do in an app, has been completely neutered to the point that you can't even create a new item from it — that is not how Mac software is supposed to work.

In 1Password 8, you now create new items from a drop down menu inside the window, but that menu isn't a real menu and if the window is too small it cuts off and you have to scroll the blasted menu — that is not how Mac software is supposed to work.

In 1Password 8, collapsing and expanding sidebar items is not animated, it just happens — that is not how Mac software is supposed to work.

In 1Password 8, drag and drop appears badly broken in the same way its broken in all Electron apps — that is not how Mac software is supposed to work.

In 1Password 8, the user cannot change or add shortcuts for menubar commands (what paltry few there are) — that is not how Mac software is supposed to work. Worse, your app steals important shortcuts used by apps like Pages.

Will any of these things, and the dozens of other foreign behaviors and UI weirdness, be fixed before the final release? I doubt it, because these are all elements that come directly from your decision to use the garbage that is Electron.
