Use case or problem
Some Wiki solutions use a hidden folder to store pictures. I use a unique system for wiki pages and for my own notes. That’s why I have a lot of pictures in hidden folders like

But they are not shown in Obsidian.
If I renamed the folder from “.attachments” into “attachments” then Obsidian would show the pictures. But I can’t do so because then I lost compatibility with wiki systems and with some other software (for example blog based on Jekyll)
I want to use a unique system for several wiki pages, for my blog and for my own markdown plain text bases notes system. I can’t change the wiki defaults, so I need to use the wiki defaults also for my own notes system.
Proposed solution
You should allow hidden folders, containing the dot prefix, to store pictures (and maybe other media files, but currently I use only pictures)
Current workaround (optional)
I think about renaming the folder and to remove the dot, but I will not do because this will not work for wiki files. Currently, I could stop to evaluate if I can use Obsidian on top of my existing notes system. Or I can proceed to evaluate, but knowing, that pictures will not be shown.
