There are now third party launchers for proton, such as: https://github.com/Open-Wine-Components/umu-launcher

As well as "game libraries": Lutris, Bottles, Heroic

Personally I use this alias to launch an exe via proton:

  alias proton='SteamGameId="${SteamGameId-1000}" PROTON_USE_WINESYNC=1 STEAM_COMPAT_CLIENT_INSTALL_PATH="$PWD" STEAM_COMPAT_DATA_PATH=$HOME/proton /usr/share/steam/compatibilitytools.d/proton-cachyos/proton waitforexitandrun'
  # cd /gamepath
  # proton Game.exe

Not OP but also wrote a similar thing for mpv.

I implemented downloading of youtube thumbnails for one of these scripts.

Here's how I use youtube, usually without opening web frontend at all:

Install mpv and yt-dlp.

Use play-with addon to open youtube or other video links directly in mpv.

Periodically convert youtube subscriptions into OPML using an userscript.

Import OPML into freetube or other RSS reader to check for new videos.

There's also DNS tunneling (dnstt) which is slow but probably harder to block

Little known but you can "subscribe" to YouTube channels without Google account by using RSS https://www.youtube.com/feeds/videos.xml?channel_id=${channe...

In fact there are 3 RSS feed types

User : https://www.youtube.com/feeds/videos.xml?user=<XXX>

Channel : https://www.youtube.com/feeds/videos.xml?channel_id=<XXX>

Playlist : https://www.youtube.com/feeds/videos.xml?playlist_id=<XXX>

thanks, but the feeds are not updated, it looks like? for example https://www.youtube.com/feeds/videos.xml?user=mkbhd lists some old videos!

Confusingly, mkbhd the user and channel are different:

https://www.youtube.com/user/mkbHD

https://www.youtube.com/c/mkbhd

For some reason though using channel_id=mkbhd doesn't work. This is a working link: https://www.youtube.com/feeds/videos.xml?channel_id=UCBJycsm...

It is embedded on the channel page as <link> element, your RSS reader should accept the web page link and figure it out.

Yes, it is best if you use the "unique ID", available in the source HTM in case the URL contains a "human readable" version.

My utility format the feed url by extracting the relevant suffix from the url slug when it includes:

"/user/"

"/channel/"

"/playlist?list="

I think the newer slug format for channels is "/c/" in which case I think you do have to extract it from the HTML source, but they now include the feed URL anyway.

<link rel="alternate" type="application/rss+xml" title="RSS" href="FEED_URL">

Are there any apps (other than Google’s own) that use these?

Any RSS app can use these feeds.

Good job! However, according to the wiring seems like it wouldn't be able to register something like ctrl+shift+z which is used as redo hotkey almost everywhere.

Looks fine to me. Did you miss the diodes?

The good thing about QMK is that you can remap anything you want to anything you want. For a hobby project, I don't know how much it would matter anyway.

Use Ctrl+y instead ;)

There's also play-with extension which doesn't require native client. https://addons.mozilla.org/en-US/firefox/addon/play-with/
