Great plugin, excellent support

This plugin has lots of blocks that are missing from the standard Gutenberg installation.
Support is excellent – the developers are responsive and appreciate feedback on ways to improve.

I run a WIMP stack and encountered a minor issue (a php warning) that is probably not present on 95% of the systems hosting WordPress, and would probably only harm functionality in a small subset of those. It was not actually affecting even me, I just noticed it and reported it.
Brainstorm took the time to understand and fix it.
I also requested that some of the dimensions be available in rems, ems and percents as well as px, and they thanked me for the the feedback and are adding that to the release cycle.
