Hi @infernoprime
Thank you for the information, the shared UI is a library for the interface, I can’t say it is the same as Bootstrap or Material Design but it is kind of similar, we use across the plugins to create the interface, similar to other themes and plugins that use Bootstrap, I wouldn’t worry about the shared UI, there is only a minimum of users that would check this file.
Also, I think you should add a preview option for the login customization screen it really helps since you cannot see it when making changes. I also hope you will be releasing another update soon since 6.0 came out.
I found it is on our Todo list and let our developers know that you are also looking for it, we don’t have an estimated time but the Branda team is working on some code updates, you can also follow the roadmap on:
