    102 == Redesign support structures ==
     102== Vector Category Index ==
    103103
    104 Reduce memory requirements particularly for points and lines. See #542.
     104Use a search tree to keep the category index always sorted and for fast insertion/deletion. This change would considerably improve the scalability when editing large vectors or adding or removing features while maintaining topology. Needs testing if a search tree is considerably faster than e.g. insertion sort.
