I had two main problems with LogSeq when I used it:
1. Not designed from the ground-up to prevent data loss. Has had data-loss issues in the past.
<strikethrough>2. An electron app that doesn't let you open multiple documents at once. (edit: nevermind, seems like they did lots of feature development here)</strikethrough>
That said, I don't know of any other good local-first outliners (i.e. like Workflowy).
