Yes

Is your feature request related to a problem? Please describe.
Clicking on the arrow next to each indent is time-consuming and similar to issue #9 is frustrating not to have a page state retained when switching pages
Describe the solution you'd like
A command line option as well as keyboard shortcuts to toggle between collapsed and uncollapsed block mode and buffer (Note/Page) mode e.g cmd + T + O block mode and cmd + A + O for buffer mode
may require having a global sate for indents in each page in order to batch toggle elements
Describe alternatives you've considered
to keep in the spirit of the application and its philosophy around notational velocity a command option for this aligns imo
