Filter Bar Lightroom classic like feature

I would like to request a new feature for the digiKam interface to improve workflow efficiency when navigating large libraries. Specifically, a dynamic "Metadata Filter Bar" similar to the implementation in Lightroom Classic. 
Proposed Functionality:
Multi-Column Layout: A set of 3–4 customizable columns (e.g., Camera, Lens, ISO, People) that can be toggled above the main image grid.
Real-Time Drill-Down: Selecting an item in one column (e.g., a specific "People" tag) should immediately update the other columns to show only the relevant data and counts for the currently filtered subset.
Visible Item Counts: Every metadata value in the filter list should display the count of matching images next to it (e.g., "Canon EOS R5 (142)").

Rationale:
While digiKam currently has powerful search and filtering sidebars, the Lightroom-style "Filter Bar" allows for a much faster, non-destructive "drill-down" experience without opening separate dialogs. This is highly beneficial for users migrating from other professional DAM software
