πŸ”₯ A new article about popups is coming next week!

In the meantime, I have created a custom popup that positions follower widget relatively to a target and prevents it from overflowing the screen.

Some of my plans for June:

- land a few updates to Sizzle starter (improved http client, tests, structure and docs)
- write RTE (rich text editor) specification (I’m planning to build editor some time I have clear understanding of all the details)
- article about Focus in flutter (tab traversal, shortcuts, screen reader, how does it work under the hood)
