Recently I began using Obsidian (1.0), it's a great little offline wiki application. What it sorely lacks, however, is an option to turn off caret blinking.
Thankfully there's the following macOS hidden setting:
defaults write -g NSTextInsertionPointBlinkPeriodOff -float 0
defaults write -g NSTextInsertionPointBlinkPeriodOn -float 4000000000
This worked for me on macOS Big Sur. I hope Obsidian adds this option before Apple kills the workaround, bless its little soul.
