The left side bar being collapsible is arguably one of the most useful features for focused note taking, one scenario is especially where you minimize the window while taking notes from a paragraph on another window.
The left side bar takes up a huge amount of space which is useful to make it a key (I am aware that it’s collapsible with the button on top left).
My suggestion is to make Toggle Left Sidebar’s default key be Ctrl + \, or otherwise have a default key anywhere else.
I think the main issue here is that right hand side special character keys don’t feature any shortcut action at all. Sidebars could be potential candidates but there are unassigned inline actions:
These days, the keyboard shortcut meta + S is no longer widely used (automatically saved by software).
Furthermore, the letter “S” can be used as a “shortcut” for Side(bar).
So, if you want a default shortcut to toggle the visibility of the right and left sidebars, I suggest these options: meta + S, meta + shift + S and meta + opt + S
This plugin has an option where you can lint the current file when you save it using Ctrl+S or :w if you use vim keybindings. You will need to turn on the setting for Lint on save for this to work.
Enabling this setting keeps you from having to manually run the Obsidian Command to a lint a file whenever you want to lint the current file.
This applies to other Linter-like community plugins as well which monitor manual file save action.
Sidebars are absolutely the bulkiest visual element of the Obsidian program, taking up half if not the entire window if the app is minimized, even if the side bars are shrunk down.
This can prove to be an issue for users who like to take notes from other windows on their desktop while requiring Obsidian to be minimized for it.
Like @blue_emperor said, I too prefer sidebars to be the only exception for this. This can turn Obsidian into some sort of sticky note rather than a fixed word processor esque software that is best used when focused or snapped to one part of the screen.
