To be honest, I did not know that a list could begin with + or * as well as - (I first used markdown in Obsidian 
).
Therefore, I did not take into account the processing of listings beginning with +.
However, when I tried it, the following content showed up in the attached screenshot in DNO’s view.
## heading
+ list begins with +
+ AAA
+ BBB
* list begins with *
* CCC
* DDD
- list begins with -
- EEE
- FFF
So if nothing is displayed, something is probably wrong.
There are several setting items related to the display of lists, but even if Show list items&tasks is turned on, normal list items that are not tasks will not be displayed if Tasks only is turned on.
Also, check to make sure that the list is not out of the display range due to various filter settings.
If it is not a configuration problem, check the following items
- What happens if you copy and paste the above sample?
- What happens if you initialize the settings, for example by deleting the DNO data.json?
- Are links and tags other than heading and list displayed?
- What happens in the Sandbox vault?
- Are there any errors in the console displayed by pressing Ctrl+Shift+I?
