One can generate the pdf and see it a few seconds later in a new tab, side by side to the markdown file.
The bad thing: I have to change the wiki links to markdown links, to get the images. And even if I do that, they are not always shown in the output because the image name is unique and obsidian dowes not add the path.
I’m quite sure your current problems with Pandoc are not unique meaning that you can find helping resources! Maybe someone here can provide help as well.
If you plan to use Shell commands plugin to implement quick pdf export to your workflow, I think you are going to use Pandoc there anyway. I’m not sure if you get any extra advantage if you use Pandoc with Shell Commands plugin vs Pandoc plugin. At least when working with shell you can apply single commands to many files at once (for example convert every markdown files in a folder to pdf files).
“Remember for this note until its closed” with a checkbox. Once clicked, it asks only one time for the correct folder and only again, if the file was closed.
