+1 for this feature and I believe we have the same reason.
To add some context for others, I’ve selected the NotePlan app folder as my vault so that it syncs automatically with NotePlan on iOS, which gives Obsidian a lovely mobile client and some bonus features like repeating tasks.
But this is what it looks like in Obsidian (Filters & com… are system folders for NotePlan)
Heh, you got it. Improved quality of life in interoperating with NotePlan is the main reason.
But there are some other use-cases. Folders of receipts, random assets used in rich media, all the “v2 v3 v4” variants of articles I produce as they’re iterated upon…
I’m on board!
can’t you use the .folder for this?
I don’t want the folder hidden on the OS (nor hidden to other apps). In this particular use case (screenshotted by @jacklaing), NotePlan uses the com.microsoft.appcenter and Filters folders for some special app magic. It wouldn’t be able to use those folders if we changed their path.
But even beyond NotePlan, I have files in my folders I don’t want Obsidian to be aware of (they cause clutter and make search results noisy, etc.). But I still want to be able to grab those files easily from e.g., Finder.
+1 I’m also experimenting with NotePlan and other apps integration using the same folder, so obviously the possibility to hide certain folders would be very handy
Another +1
I, too, am playing with integrating NotePlan and Obsidian. 
This would be helpful for those of us who aren’t interested in seeing notes such as templates or attachments.
‘Right-click > hide’ would be great, with an option to ‘show hidden files’ when needed.
Yes, urgently!
I’m parsing .md files before pushing out to git. I’m therefore having a duplicate of each file. Obsidian hence insists on fully qualified links. I’ve tried chflags hidden but obsidian choses to ignore it.
Thanks!
+1 It’d be really useful
+1 too. Thank you for your consideration.
+1. Would be very useful to ignore specific folders within a vault, specially during operations like searching and moving file to other folder.
Thanks.

I need this feature too.
I like to add .obsidian to my development project’s folder, making them a Vault, but it would be nice, if I could keep some stuff out of view in the GUI and not have them getting processed by Obsidian.
This wouldn’t really help my issue with the templates folder going into the Vault’s root, however, since I want to hide that from the project’s root folder, not from Obsidian. If you also would like the templates folder to go from the Vault’s root into .obsidian, please show your support at Place ‘templates’ folder in ‘.obsidian’ but expose to UI. Thanks.
This is a great feature request. I would also add the option to select whether one can still search & embed notes/images/other data from the hidden folders. Also through a right-click menu, something like Keep this folder searchable.
As hidden asset folders are not supported currently I went with a workaround. I posted this in a similar thread: Show / hide file types to be shown in file explorer - #17 by cmprmsd
I would like this for sure. But there is also the situation where you might want a folder to not be indexed by Obsidian. I have a few reference library folders that I never add to or change but often have to wait while Obsidian heats up for a minute or two when I boot the vault up. Sorry if this is unrelated. Maybe I should do a feature request.
Thanks.
+1 for this. Meanwhile I got used to the file tree plugin which has an option to add to “excluded folders”.
+1. It would be really useful
