Ah okay, that makes a lot of sense for the group sections.
I changed the group back to extras and now it does show up, but now it along with the existing options cog dropdown the same menu.
api.onToolbarCreate(toolbar => {
toolbar.addButton({
id: "align_center_button",
group: "extras",
icon: "align-center",
popupMenu: true
});
});
Would this be a possible feature to add to the plugin API? The ability to add custom items to your own dropdown independent of the existing options dropdown. I could see this being useful as our composer is starting to look a little cluttered with all the additional options we would like to have
