Issue
A plugin, panel, or command used in the classic Studio layout is no longer visible.
Cause
The next-generation UI reorganizes tabs, windows, and toolbar customization, and preview builds may not match the old layout exactly.
Fix
Use Studio search or the relevant tab to reopen the panel, then add frequently used actions to a custom toolbar when supported. Verify plugin compatibility and update the plugin before resetting Studio settings.
Verify
Restart Studio and open a second place to confirm the tool remains available outside one saved layout.
