Dear Reinhard, I wouldn't say "solely from the detector side". The biggest improvement is synchrotron radiation (+2D detectors🤓).

This would make routine work much easier. IMHO, the biggest improvements in XRPD instrumentation within the last decades came solely from the detector side, should be continued. Regarding search-match by Rietveld: Your FSPM method is a very inspiring idea. Nicola Doebelin has incorporated a simplified approach in PROFEX, too: https://www.youtube.com/watch?v=Oqj71TiifeI I'm routinely applying a run of ~500 structures/minerals what we are commonly using (+- the former QPA database of Seifert AUTOQUAN or from the BGMN webpage) for a phase screening of unknown samples, needs ~ 5 min without interaction. Than running QPA refinement with the best matching structures, clicking on remaining peaks in the difference plot for getting a proposal of best matching main line positions in the database, and adding these structure(s) to the refinement, running again... This is a typical workflow in our lab, no need for peak search, background treatment, thinking about artifact peaks...
