Having worked a bit with the Card List Editor, I found some annoying things that I definitely needed to fix: First, adding a new card or editing an existing one no longer causes the whole list to be refreshed. Second, even if the list has to be refreshed, i.e. you’re loading a new card list, a progress bar is shown indicating how long it’s gonna take. Third, the tool now provides a function for automatically sorting the list and assigning new indices to all cards.
