Better visibility that the bom list is filtered to avoid confusion and incomplete exports

The feature of bom F/B filtering is nice but not that visible. I think I saw questions about that filtering of bom list in the forum - what is already supported. I can imagine that some pcb designers hand out only the ibom to assembly partner and they then use the ibom export to generate the final bom for importing to their process. If the bom is filtered by the filter field this is much more obvious than filtered/incomplete list by the F/FB/B buttons.

I have no final suggestion - this is more to discuss it and get some opinions.

Would a solution be a syntax for the filter field that it is more obvious that a filter is active? Example (but this has the consequence to extend a parser for this syntax)

Or there would be enough space to add a button-like UI feedback that a filter is on like this (not nice just a mock):

Clicking the button would disable the filter and it disappears.

Or splitting visual and list filtering and present the same F/FB/B buttons in the filter line?

No files, tests, or entry points are identified in the issue. First review the BOM filter UI and export behavior, then agree on one visibility approach and define done as making active filtering obvious without producing confusing or incomplete exports.
