If you just want different display preferences, changing columnselection_pref would be better.
We mess with it a bunch and apply some suffixes to it to store visible columns, column widths, letter search, etc. Infolog uses it for details / no-details, but it’s better just to set it once.
dataStorePrefix is used for client side caching, linking & push updates and should be an application registered in the link registry. If your rows are genuine infolog entries and your ID 4 = Infolog ID 4, you should leave it as ‘infolog’ so all nextmatch widgets that show infologs can share the same cache, and all the automatic stuff works. If you consider these different data, you need a different dataStorePrefix (which defaults to your application name).
It is possible that the projectmanager elements doesn’t work, because as you point out elsewhere they don’t match.
