X Left off Bookmark par Fernando

Built for a news-only X account with notifications on.

When the flood of posts keeps pushing everything down, it's easy to lose where you stopped reading. X Left-Off Bookmark fixes that — like a bookmark in a book.

What it does:
- Mark here button saves your spot
- Go to mark jumps you back to it
- Blue line shows ▼ YOU LEFT OFF HERE ▼
- One mark per place — Notifications has its own, Home has its own
- Saved on your computer only, stays after restart

How to use:
1. Go to Notifications or Home on X
2. Hit Mark here when you need to stop
3. Come back later, hit Go to mark
