I can’t place them to the right of the “gear” icon. They can all be placed between emoji and gear. What icon is most important to you ?
The best way would be to hide some specific icons, I explained the process here : Formatting toolbar
Or you could fork the plugin on github and customize it a little, I can explain the process if you’re interested
But I don’t know if changing the plugin for everyone is the best solution here, I don’t have a lot of feedbacks, but it seems that the choices I made were appreciated. If there is a recurring request to delete some icons or reorganize it, I’ll do it.
