I ask because currently (fb2k 1.4.2 beta 1, but IIRC behavior always was the same) UI element "Selection Properties" seems to ignore "Always preload complete info up to N tracks" setting.
For example. I have "unsyncedlyrics" added to spam fields in LargeFieldsConfig.txt. unsyncedlyrics is added to Standard fields in advanced settings. Advanced->Display->Properties dialog->Always preload complete info up to N tracks is set to 100. So In Context menu->Properties i can see content of unsyncedlyrics field. But UI element "Selection Properties" refuses to follow this setting (Always preload complete info up to N tracks is set to 100) and shows only dot instead of content of unsyncedlyrics field. Is it supposed to be this way?
Selection properties is meant to show cached info only, it never accesses your files. This is by design.
