It would be really great if you’ve implemented hidden folders support for attachments.
Initially I used Typora with option of creating .filename.assets folder in the same directory with filename.md file. This is very convenient comparing to using a single media folder for all attachments. If you delete the file, you can easily delete all the images and attachments.
Please, consider implementing this feature, it would be really great and shouldn’t be hard to do.
Thanks in advance!
