Sure.

But like, the author's got some Bad Habits they are trying to bring over, and seem to consider their inability to replicate them as a problem?

I can’t find official apps for Airtable (which I use for work), Spotify, or Apple Music, but they all work fine in the browser in the short term, and I’ll revisit this later.

So, "I have to run these websites, that I used to run in dedicated memory-hungry Electron apps, in a browser instead" is something that's missing? TBH, seems like a feature to me. Heck, things like Discord and Spotify run better in a firefox derivative than they do as "standalone apps" on any OS, Windows included.
