Seeing what other apps have done, there are so many more cool possibilities.
Tools – Widgets would allow you to open up a specific tool directly with one touch, rather than the 3-5 it currently takes. And to be able to customize which 4-8 are always on top would be nice. Also, see the Google search widget for how you can have a basic search AND three guide searches all be launched from the same widget.
Memories – could be really cool in the context of prayer lists, note creation date, past sermons, etc as a way of reminding you of what God has done for you or reigniting past thoughts you jotted down in notes. Day One and Photos "on this day" are a good example
Layouts – Drafts 5 also is a great example of how workspaces (similar concept to Logos layouts) can be launched directly from a widget.
Dashboard – Various news app show how Logos can spotlight resources/excerpts within your library like they do on the Home Screen on the desktop. Wikipedia has some cool “picture of the day”, “on the day”, and “top read” widgets that Logos could implement. For example, “On this day” could be various Old Testament feast days, “Picture of the day” could be media excerpts, and “top read” could be a variation of community notes/highlights.
Progress – The iOS battery widget and Streaks show how reading progress for a given book or progress made on a certain workflow could be very useful.
Today – think to-do lists, but for reading plans and workflows. The iOS files widget is a great example of how you can display 1, 4, or 8 resources on a widget.
