Comments
CutePeaks is a lightweight, cross-platform C++/Qt5 viewer (published in the Journal of Open Source Software) that fills a similar niche to 4Peaks on Windows and Linux as well as macOS. Its clean SVG/PNG export and regex motif search make it handy for everyday inspection and figure preparation.
