We are very close to merging (this PR has now been merged) a pull request into the 1.20 branch of Backdrop CMS that will make it possible to create simple recipes in the form of modules with nothing but a .info file and a batch of config files. While not trivial to create, these "recipe" modules could in theory be downloaded from BackdropCMS.org, installed through the UI, and enabled just like any other module.
Audience: developers creating forms programmatically
For many years now, I've been using #states in many of my pull requests that were around improving the admin user interface. I've found that hiding/showing form elements depending on various conditions, in many situations may result in a much better user experience for content editors and site builders using Backdrop.
We have been experimenting with the use of a Mural Board for the upcoming Backdrop LIVE.
MURAL is a digital workspace for visual collaboration, where everyone can do their best work together.
In other words, a Mural Board is a fancy virtual white board that can be used for collaboration and facilitating virtual meetings.
Backdrop LIVE is March 12-13 (or 14th in some places)
