Doesn't limit your widget slots
The cool part is it only needs to offer one widget of each size for the home screen and everything else is done through widget options. You add the wallpaper you're using in the app, place one of the widget sizes in your home screen, hold/tap to edit its settings, tinker with everything you want to change and bam! Instant blank widget! (If you change your wallpaper often, choose a name like "current" to give to your current wallpapers and set all widgets to "current". Then whenever you switch, call the new wallpaper "current" and all widgets will switch to the new background!)
It has a blank name, so it's blank both in small and in large mode (and switches background as soon as you switch the mode).
If I had to pick one way to improve this, it'd be to let us select fonts for the text. Even five fonts can make a huge difference if they're well chosen! It'd also be amazing if there was a shortcut action (or url scheme) to switch files/wallpapers because I like randomly switching my wallpaper with Shortcuts, but I know that's a big thing to ask for so I understand if it can't be done.
