Cons
Con Little bit of a learning curve
If you're not familiar with VSCode, there may be a steep learning curve.
Con No mobile app
Dendron runs in VSCode so no ou-of-the-box mobile sync/experience.
Con Obtrusive, like someone WITH CAPS LOCK ON
Too loud, too much going on, and definitely an in-your-face sort of feeling.
