I went through all the past topics like these (examples) from 2020, 2021, 2022, and tried every single one they mentioned, and all failed (and failed pretty spectacularly). but why is it 2023 and NOTHING like this exists? I don't think the above by ANY stretch of the imagination is crazy things to ask for in a video player.

Need simple options like adjusting the subtitle font size so it doesn't take up a the lower ~20%! of the screen, and simple quality-of-life things like keyboard shortcuts to skip forward/backwards quickly and raise/lower volume. I need a standalone video player to play HDR videos in all the common formats (NOT in a browser fyi, that doesn't work for my workflow).
