Feature Request / Bug Report – ExtendScript Filter API broken in Bridge 2026

Hello Adobe Bridge Team,

I would like to report a missing/broken feature in Adobe Bridge 2026 regarding ExtendScript filter control.

PROBLEM:
In Bridge 2026, it is no longer possible to control the Filter Panel programmatically via ExtendScript. Specifically:

• app.document.filterParameters returns null (was functional in older versions)
• app.document.chooseMenuItem() does not trigger rating filters (e.g. "Rating3")
• thumbnail.selected = true/false has no effect on the visual filter
• app.addEventListener() is not supported in Startup Scripts context
• MenuElement("separator", ...) throws "Bad argument undefined"

USE CASE:
I use TouchPortal (a hardware/software button panel) to control Bridge remotely. I need to be able to toggle filters for specific star ratings (e.g. show ONLY 3-star images, additive with other ratings) via keyboard shortcut or script — without using the mouse.

The existing keyboard shortcuts (⌥⌘1–5) only support "X or more stars" (>=), not exact star ratings. The Filter Panel checkboxes for exact ratings are only accessible via mouse click — no keyboard shortcut, no script API.

REQUEST:
1. Restore filterParameters API functionality in Bridge 2026
2. Add chooseMenuItem() support for individual rating filter checkboxes
3. Add keyboard shortcuts for exact star rating filters (not just >= filters)

This functionality existed in earlier Bridge versions and its removal significantly limits automation and accessibility workflows.

Thank you for considering this request.
