Perhaps I am missing something here and other users with more experience of Blocs know the answer, but I am having a go at a first website for a client using Blocs and the theme of the website is chocolate making.
The client wants elements of chocolate colours and if you end up with 5 varieties of chocolate brown the colour organisation becomes a bit of a headache. Simple named tags would solve that.
In Freeway I recall being able to label colours with a personal tag that made sense while building a website and I’d like to see something similar with global swatches. Changes to global colours will naturally affect other parts of a site, so to avoid this you then end up potentially creating more colours than necessary, which adds to the confusion.
This wouldn’t need to be ugly or cluttered. I am sure an elegant, but functional layout could be developed.
