If you start writing a new post, you will see the right-hand side bar with many options, such as the categories list. These mostly have expand/close options (V and up-V controls). These are remembered per user. It would be good to set the default state of these.
Also the three vertical dots icon reveals the user’s choice of whether to use the Top Toolbar, Full window mode, etc. etc.
It would be good if the state of these could be saved for users who have not set their now or new users, as did FV Clone Screen Options.

thanks
