Hello, Please leave the Emacs' default value of "bidi-paragraph-direction" which is "nil" in orgmode as well. Right now orgmode seems to force "left-to-right", thus blocking "right-to-left". With "nil" it is dynamic, which means both directions work well out-of-the box.
Right now I'm forced to add this to my config: (add-hook 'org-mode-hook (lambda () (setq bidi-paragraph-direction nil))) It took me a lot of time to figure out, which makes the first Org steps for RTL-newbies quite frustrating... Please, let me know if you decide to fix this in the upcoming versions. Thank you!
