I personally couldn’t give a crap about those kind of things, I definitely wouldn’t pay for it. Mona looks great and is already customisable enough for my liking. Some other apps have even more visual customisation.
If I wanted a custom theme in my web browser I’d run custom CSS, like how Bird UI works. Or just use a service like elk.zone and I wouldn’t have to faff around with custom themes/code/plugins.
But sure, I don’t see why you couldn’t do this. It’d be best done via plug-ins for Mastodon, not per-instance. Then people can off plug-ins in some kind of marketplace. You pay for the plug-in, it installs into Mastodon, and you can manage your current plugins from your Mastodon preferences.
Yeah, why not. If someone wants to build it then there’s no harm in it existing.
Sean, this article is really reaching.
