Hi HN, I built FastPlay, a Windows video player focused on the parts of playback people actually notice: fast open, quick first frame, responsive seeking, and simple local playback. A big part of the experience is keyboard-driven control, so keybinds are first-class: space to pause or replay at end, left and right to seek with accelerated hold behavior, subtitle toggle, auto-replay toggle, fullscreen, zoom, rotation, and fit-to-screen controls. It is still early, but there is already an MSI installer so it is easy to try on Windows. I would especially love feedback on startup speed, seek responsiveness, playback feel, and whether the keyboard-first direction makes sense.
