This +1. Really helps me too esp when I used to have my SB organized on Dropbox Paper (I made a network of individual Papers linked together).
I am starting to move my SB to Obsidian with my vault hosted on Dropbox, so I can sync & edit on my iPhone with 1Writer. Works really well, except that Dropbox encounters sync issues with emojis in the .md note file names (e.g. notice tiny red X icon on bottom left below which indicates that it is not syncing) [edit: I just noticed @cotemaxime already addressed this and faced the same issue].
Not syncing

Synced

Note: syncing with Google Drive instead does solve this problem, but encounters other sync issues with iOS file system for some reason, making Google Drive unusable for my two-way PC/iPhone note syncing system.
My current “workaround” is to have headers on top of each PARA item/note where I can slot emojis, e.g. Areas>Health note would look like below:
Health (this is the note header)
Obvious downside is that you still can’t see the emojis in your file navigation panel on the left pane, but I am trying to develop a “Control Centre” note that serves as my PARA-indexed landing page every time I launch Obsidian, where I then have links to all other PARA-related sections and notes, making the file navigation tab redundant for me (basically replicating my Dropbox Paper workflow, with the added advantage of Obsidian automatically updating links, and of course system-agnostic data ownership)
Hope that all made sense! Happy to share more once I have a setup and workflow that works well for me if any interest. First post btw, and loving Obsidian + community so far.
