> Ideally, I select a file, information appears on my tag panel which includes a 'miscellaneous metadata' field, and I immediately see only the handful of straggler tags rather than the 25+ fields that would likely pop up if I hit ALT+T. No extra action nor effort required for comprehension of what I am dealing with. I will immediately see other stuff I might be able to utilize to flesh out my regularly existing fields, or what I might want to cull, etc.

This is possible now with the `_FORMAT` field like @ohrenkino suggested. But it's complicated if you are not comfortable with deeply nested expressions and regular expressions.

> useful for multiple-file selections IMHO. I frequently use the indicator in both my Tag Panel and Extended Tags to figure out which files have matching metadata in a quick-and-dirty way, but there's often one or two files that are the odd one out.

However since the `_FORMAT` field, even when containing multiple tag-value pairs, is still only one field, it does not help for multi-selections as only the entire field content is compared, not each tag-value it consists of.

Here's a video to show you exactly what I achieved going off of @7stones's idea and where the limitations are.

The code that creates this behavior isn't for the faint of heart and it's also specific to how I configured my tag panel.

```auto
$replace($regexp($regexp($regexp($regexp($sort($regexp($regexp($list(🦕,:$repeat($char(9),4),🦖,\\),🦕(?:album(?:artistsort|artists?|sort)?|artist(?:sort|s)?|barcode|catalognumber|co(?:mment|mposer|pyright)|description|dis(?:ambiguation|cnumber|csubtitle|ctotal)|genre|isrc|label|lyricist|mediatype|mb_artistcredit_artist_country|musicbrainz_(?:(?:album(?:artistid|id|releasecountry|status|type))|artistid|release(?:groupid|trackid)|trackid)|originalyear|publisher|setsubtitle|title|track(?:total)?|version|year):\t'['^🦖']'+🦖,,1),(?<=🦕)('['a-zA-Z_ #\d']'+:\t++(?='['^🦖']'{68})'['^🦖']'{67})'['^🦖']'*,$1…),🦖),\r?\n,↵),(?<=🦕)('['^:']'{1','31})(:\t+'['^🦖']'{1','36})(?=🦖),\U$1\E$2\r\n),(?|(?<=🦕)('['a-zA-Z_ #\d']'{32','}:)\t+('['^🦖']'+)(?=🦖)|(?<=🦕)('['a-zA-Z_ #\d']'+:)\t+('['^🦖\n']'{36','}))(?=🦖),\U$1\E\r\n $2\r\n),(?<=🦕)(?|('['A-Z_ #\d']'{1','7}:\t{4})\t*|('['A-Z_ #\d']'{8','16}:\t{3})\t*|('['A-Z_ #\d']'{16','23}:\t{2})\t*|('['A-Z_ #\d']'{24','30}:\t)\t*|('['A-Z_ #\d']'{31}:)\t*),$1),🦕,,🦖,)

```

It adds a filter to [this](https://community.mp3tag.de/t/listing-all-tagged-fields-in-the-tag-panel/71949/9) solution for displaying all tags in a single `_FORMAT` field early on to keep the performance acceptable (but even in the video you can see a slight flicker after selecting the third track because of the long `LYRICS` field while the `_FORMAT` field is evaluated).

However I'm sure you or 7stones can build a less complicated version if you have fewer tags in your tag panel and/or are not as picky about the horizontal padding as I am.

For me, being able to quickly flick through the tracks and seeing only the nonstandard tags in one place is good enough to find tracks that are missing a tag or have more than others.  
I'll add this version with a breakdown to the linked thread. Edit: [Done](https://community.mp3tag.de/t/listing-all-tagged-fields-in-the-tag-panel/71949/10).
