These indexFormat options would be applied from left to right to each item (track or group) and would not replace any existing tags in the item. For example, if you specify

workbytitle.indexFormat={$title$tonality$opusnumber$subtitle}

this would add a workbytitle tag if it doesn't exist in this item. No tag would be added if the item already has a workbytitle tag.

The processing of indexFormat would occur later than the processing of tagOptions and tagValue, so any new tags created by indexFormat would not have tagOptions or tagValue customizations applied to them.

When processing the tags in the format string, the index values of these tags will be used.

If a custom sort value has been applied to the first tag that is processed by the format string, this custom sort value will be applied to the new tag that is created by indexFormat.

The processing of indexFormat would take place while scanning the library. This is unlike displayFormat processing, which takes place during browsing. If you have a large library, the overhead of doing indexFormat processing might increase scanning time significantly.

Would this enable you to do what you want?

First of all, many thanks to come up with a concrete and very detailed design proposal. I had to think a little bit about it. From all what I see, your proposal would satisfy all my needs.

If it would simplify implementation, special handling of customized sorting could be left away. Default sorting (alphabetical, numerical) would be sufficient - at least for my concerns.

I would be very happy seeing it implemented in one of your next releases. Thanks a lot in advance!
