  Among several ideas which arose as consequences of modular localization there
are two proposals which promise to be important for the classification and
construction of QFTs. One is based on the observation that wedge-localized
algebras may have particle-like generators with simple properties and the
second one uses the structural simplification of wedge algebras in the
holographic lightfront projection. Factorizable d=1+1 models permit to analyse
the interplay between particle-like aspects and chiral field properties of
lightfront holography. Pacs 11.10.-z, 11.55.-m
