I don't really want to throw a lot of options in the overflow menu that most users wouldn't need to change. What about another approach such as making the toolbar collapsible? Something like, you tap an icon to collapse it, and then a small icon shows up at the very bottom beside the alphabet list? Another change that I'm going to be considering is moving the entire filter section to a side panel that will be expandable/collapsible using a hamburger icon at the top left (kind of like what the Google Play Store has). This will open up a lot more options for the filtering such as letting users reorder the filters, choose which ones should be present, and handle translated words better. In theory I could have an option in this side panel for the floating toolbar to show/hide it. Let me know which of those two you prefer, or if you want to explore other ideas.
Thanks,
Mike
