How to customize the composer toolbar?

Feature

I also have older folks on my forum, and I feel silly explaining this to them.

The gear is also a very non-obvious symbol for “there’s more”. Maybe an ellipsis would be more appropriate? Is there a straightforward way I can change the icon?

Another stumbling block I found here is that on mobile there is a little hamburger icon that hides/shows the toolbar, and it seems to be off by default. This causes way more confusion than any benefit it could offer. I turned it off:

.composer-controls .toggle-toolbar {
  display: none;
}

.d-editor-button-bar {
  display: grid !important;
}
