For the last couple of months I've been working on something and I'm excited to finally share an early preview:

Say hello to plumber2 🎉

plumber2 is a full rewrite of the plumber package for creating powerful webapis in #rstats. It takes everything we have learned from plumber and adds even more

Just merged a PR in {mapgl} introducing some long-awaited updates to the layers control.

It now has an improved appearance that takes up less space by default, and you can customize its position and styling as well!

Install from GitHub to try now; it'll be in the next CRAN release.
