P: Modal dialogs should not completely halt export and other background tasks

Hello Adobe Team and Community,

I am submitting an idea to solve a critical workflow issue in Lightroom Classic: any modal dialog box completely pauses all ongoing background processes.

**The Problem (Description):**
When a long-running background task is active (like exporting thousands of photos, importing a large shoot, or building smart previews), a simple modal dialog box can appear unexpectedly. For example, the "Enable address lookup?" or a face detection confirmation. When this happens, the background task is completely halted and remains paused indefinitely until the user manually dismisses the dialog.

**Why Fixing This is Valuable:**
For any professional user, this is a major disruption. If I start a 5-hour export and step away from my desk, the entire process could be stopped 10 minutes in by a simple pop-up. This defeats the purpose of background processing and forces me to constantly monitor the application. It severely impacts productivity and makes it impossible to run essential tasks unattended (e.g., overnight).

**The Idea (Proposed Solution):**
I propose that non-critical notifications should be non-modal and should NOT pause essential background tasks. Possible solutions could be:
1. Display notifications as non-blocking pop-ups (toasts) in a corner of the screen that don't require an immediate response.
2. Create a "Notification Center" within the Lightroom UI where all these requests can queue up, waiting for the user's attention, while allowing background tasks to complete without interruption.

This change would be a massive quality-of-life improvement for all serious Lightroom Classic users.
