The electron stretcher accelerator facility (ELSA) at the University of Bonn utilizes a storage ring design to deliver a continuous 3.2 GeV beam of polarized and unpolarized electrons to external experimental stations. Alongside its main purpose to service the hadron physics community, additional modes of operation are developed to allow versatile usage for accelerator-, detector- and medical research. Current developments in beam polarization enhancement, beam diagnostics, electron source and permanent magnet design as well as modification of beam extraction schemes for medical research and a more economic usage for the detector testing community are presented.
