Hi @EbrahimH and the others,
After facing this exact same issue, I took some time to invest in a solution (should be easy when using Cursor 
)
I wrote an extension that understands the structure of the Chats window and the Plans Markdown window and applies RTL when needed.
The extension is smart; it detects which language the sentence starts in and applies the alignment accordingly.
For now, the installation is only using a VSIX file. Please see the instructions here: Cursor RTL - Smart Multi-Language RTL Support
Itās fully open-sourced, so you can investigate and use the code as you wish.
Have fun
