How to show only input area? I tried full screen, it’s not what I want - I want just a notepad-styled “zen” mode as side-bar when I’m in reading , so that I can take quick note.
Now I can only use other notepad, and copy-paste into Obsidian.
You could try the Hider plugin (I haven’t used it myself).
If you just want to hide the side panels, use the arrow-heads at the the upper left and right of the window (they’re hard to see in the default theme — I didn’t know they were there at first) or open the command palette and type “side” to bring up the sidebar commands…
