macOS: Show Vorta in Dock / Cmd-Tab while main window is open

[QuirkyTurtle94]

Hi,

I'd like to propose a small macOS behavior change for Vorta and wanted to check whether this fits the project before opening a PR.

Current behavior

On macOS, Vorta is packaged as a menu-bar / accessory app using LSUIElement. As a result, when the main Vorta window is open, the app does not behave like a normal foreground macOS app, leading to a few UX issues:

• it does not appear in the Dock
• it does not appear in Cmd-Tab
• it is harder to switch back to the open Vorta window using normal macOS window/app navigation

Suggestion

Keep Vorta as a menu-bar app by default, but when the main window is opened, temporarily switch the app's macOS activation policy to regular app behavior (ie tabbable, shows in the dock). When the main window is closed, switch back to accessory/menu-bar

Possible implementation

On macOS this can be done with the native activation policy via PyObjC/AppKit:

• NSApplicationActivationPolicyRegular when opening the main window
• NSApplicationActivationPolicyAccessory when closing the main window

This would avoid changing the packaged LSUIElement behavior globally, so Vorta would still start as a menu-bar app.

I have a local prototype for this approach and can open a PR if this is a direction maintainers would support.

Questions

Would this behavior be acceptable for Vorta on macOS?

If yes, would you prefer this as:

1. the default behavior whenever the main window is open, or
2. a user setting?

Also, should this PR stay focused only on Dock / Cmd-Tab visibility, or should it also add/adjust standard macOS app menus such as File, Edit, and Window?
