This is pretty simple.
Usually, when I want to open a new note, I almost always want to keep my previous note open. Ctrl + N opens a new note, but takes me away from the note I am in. I would like to by able to hit either Ctrl + N or Ctrl + Shift + N and open a new note in a new pane.
If you would like this too, or would like a variation of this, please let me know!
+1 It’s hard to believe that this isn’t a feature already! I had to check, haha!
Me too!
For those on windows using Auto hot key, current workaround I have is this
#IfWinActive ahk_exe Obsidian.exe
^+n::
Send ^pSplit vertically{Enter}^n
return
This will split the pane vertically and create a new file.
Another emphatic +1
Nice, never thought of that!
