Hey everyone 
We’ve been building Bubble plugins at Minimum Studio for a while now (since 2018) & made quite a few (100+) over the years. About a year ago we decided to step away from selling plugins completely.
These days, when we build something useful that we can extract from our work, we try to make a plugin out of it and share it for free. You can find those on our contributor profile. We’ve launched a few new free ones recently as well.
Instead of building plugins commercially, we decided to put all our knowledge about building plugins into a course. We launched it a few weeks ago on Twitter and got tons of positive comments & feedback from real students, which made me feel good enough to share it here too.
You can find all the details and course outline here 
Mastering Code & Plugins In Bubble
I created a coupon code FORUM for $50 off to match the promotion we did on twitter as well.
Lastly, here’s a few tweets showing the kinds of plugins that are featured in the course.
