Since I received multiple questions, here's the plan for the remaining minimal support extensions:
Most extensions that were previously compatible with Flarum beta 16 require only 15-20min of work to be updated and tested for Flarum 1.0.
Based on the number of extensions remaining, that's probably around 3 hours of work remaining.
Unless I need those extensions for a personal project, the extensions won't be updated. I might update a few during my live streams, but that won't be before a few more weeks.
If you're interested in sponsoring those updates, it's 50CHF or USD for one hour of work, which is good for 4 extension updates of your choice. You can sponsor via GitHub Sponsors or I can send you a Paypal/credit card invoice. I'll add the sponsor names to the extensions they sponsored. I'm not doing less than 1h, as it's too inefficient.
You can contact me via the email on my website or on Discord.
