These are key features that are missing in order of importance.
No search panel to search JUST the current stack (the 'stack:' command does not seem to work anymore either)
Cannot lock important reference notes to prevent inadvertently editing of key information
Cannot set custom date formats (that order properly when listing)
Cannot create code blocks
Cannot set custom colors that match those my company uses.
Cannot set the order of the icons for editing, lists, etc.
