audacious VS mdBook

I usually just use mpv since it's the simplest and most flexible. You might be looking for something like Audacious though, which is great too

Audacious is a more popular media player app that supports Winamp skins and a media library.

This may interest you,and it is Qt,plus can be used with MPD. https://audacious-media-player.org/

the new version of audacious has a vu meter and its also available to windows https://audacious-media-player.org/

Audacious audio player.

Find a GUI player you like (see https://wiki.archlinux.org/title/List_of_applications#Graphical_13 for a non-exhaustive list; ISTR Audacious being mentioned as a Winamp clone) and add it to your autostart items (see https://wiki.archlinux.org/title/Autostarting#On_desktop_environment_startup).

Yes, Winamp works well on Linux through wine, I have been using it for a long time myself. Although recently I have also been using audacious, which runs more smoothly and is better integrated with Linux (as it is a native application) and it also has support for Winamp skins, so it's a fairly good drop-in replacement (as long as you're not relying on some esoteric plugins or file formats).

im not the parent commenter but i highly recommend audacious for linux and windows. plays every audio format you have, doesn’t enforce a specific music library folder structure, and supports winamp skins(!) https://audacious-media-player.org/

... which is under active development/maintenance.

I'm responsible for a number of Java products. I try to provide high-quality Javadoc for all public library interfaces, library user's guides where appropriate, and development guides for applications. The latter two take the form of MDBook documents (https://rust-lang.github.io/mdBook/), with the document source living in the GitHub repo so that it's tied to the particular software release in a natural way.

My org has used mdBook: https://rust-lang.github.io/mdBook/ (That link is itself a rendered mdBook, so that'll give you an idea of the feature set.)

(While it's definitely a Rust "thing", if you just have a set of .md files, all you need is a "SUMMARY.md" (which contains the ToC) and a small config file; i.e., you don't have to have any Rust code to use it, and it works fine without. We document a large, mostly non-Rust codebase with it.)

If you want the lowest friction, open source, easily extensible Markdown to Web, Kindle, PDF, etc. tool, highly recommend mdBook: https://github.com/rust-lang/mdBook it’s written in Rust, but you don’t have to know any Rust to use it. And then wing is all CSS; for which there are many good (free) themes.
