[FR] Make ### Modified header optional

[jfgrtsn]

First Steps

• [x] I've ensured that this feature request does not already exist by using the search issues feature
• [x] I've read the documentation (see the README)
• [x] I'm on the latest release of obsidian-list-modified

Describe the desired feature

Current behavior is to create a Modified section (H3) below the Primary Heading and list modified notes under that heading. I would like the option to suppress that sub-header and just list all created/modified notes under the main heading. There are on/off switches for Created and Deleted sections, but not for Modified.

Possible alternatives

I tried setting the Modified heading name to blank, but it still creates a line with just "### " (blank H3).

Additional info?

I understand you're trying to make the plugin flexible, but please make sure it can still handle the basics. What I'm going for is simple:

## Touched
