I use a very minimal interface in Joplin, having hidden most of the button. This has caused me to notice that the Note properties is not found in the app menu system. I would have expected to find it below or above Note > Statistics…
Without that the only way to access it (without the button) is to use the command pallet.
Sorry I didn't explain well enough. I have hidden all the tool bars. I don't do much formatting and I'm on a smaller device. So I don't have that icon to click on.
Also for keyboard users, it makes sense to have in in the menu system.
