From a quick search:
- [FR] Characters per line adjustment
- Adjustable "Readable Line Length"
- A fix for ugly long lines in fullscreen v2
- A fix for ugly long lines in fullscreen v3 - Readable Line Length Customization
- Features supporting maximum character count in a line
- Readable line length should scale with font size
I’m aware that developers are overwhelmed with requests, but it’s not an issue that’s complex to address and may be viewed as a basic feature that’s missing. For instance, IA Writer is purposefully designed to offer only essential customization options. Still, line length (with ample control) is one of them.
Calmly Writer is even simpler and surpasses Obsidian in this regard.
