[Feature Request] Display tag information without writing it

Development Web Sources Discussion
1

Just an idea to be able to display retrieved tag information without ultimately writing it to any files.

For example, we could use any output buffer name prefixed with _mp3tag, e.g. set _mp3tag_sometag, and have its values display in the "Adjust tag information" window, and upon OK, Mp3tag would automatically omit such prefixed output buffers from being written. These temporary buffers would function the same as any other buffer in a script, but simply be disregarded before writing.

A use case:

I want to write a bunch of returned ISRC values, one per track, but the list of ISRC values alone provide no context regarding the listed files on the right (without referring to the source website for example). If one could have a _mp3tag_track and _mp3tag_title output buffer listed along side the ISRCs, it'd provide context and sortability, thus reducing errors writing the tags on the left to the wrong files on the right (which is possible to mess up even with context at times, for example, when attempting to tag a wrong number of tracks). Seeing the track titles/numbers would help when writing a single type of field, such as only genres, or only some UUIDs. Hopefully the UI could also help indicate that a given column won't be written (dimmed/italic values, something visually differentiating).

Thanks!

This would be great! +1 :+1:

If you want to write only 1 (or very few) tags back to the selected local tracks, it would be very useful to have more control about the tags.

For Example: If you only want to write back a single YYYY-MM-DD-Date, the user should be able to match his local tracks in the metadata "Adjust tag information" preview window. This is only possible if the tracknumber and title and length is visible. But only the Date should be written into the local track. No tracknumber, no title.

O.K. This would be a nice feature.
At the moment I use a workaround for typical cases, i.e. adding the composer for all my files.
So I have an edited websource-script as duplicate that only grabs the composer, and for being sure to write the content to the right files, I leave some tags-fields as TRACK, ARTIST, TITLE and the length and redirect them to TRACK_TMP, ARTIST_TMP ...
Later I clear these TMP fields in 1 action for some days work.
