Hello @KhaledEmad7,

thank you very much for submitting this PR to us!

This is what will happen next:

1. My robotic colleagues will check your changes to see if they break anything. You can see the progress below.
2. Once that is finished, human contributors from paperless-ngx review your changes. Since this seems to be a small change, only a single contributor has to review your changes.
3. Please improve anything that comes up during the review until your pull request gets approved.
4. Your pull request will be merged into the dev branch. Changes there will be tested further.
5. Eventually, changes from you and other contributors will be merged into main and a new release will be made.

Please allow up to 7 days for an initial review. We're all very excited about new pull requests but we only do this as a hobby.
If any action will be required by you, please reply within a month.

Thanks. As this is our first RTL lang in the UI I wasn’t sure if the UI would need other adjustments. Did you find it still legible, usable etc?

[shamoon]

Thank you for the PR. We'll merge this for now, there's been some issue with the arabic translation file Im trying to sort out but it does look like the UI is largely translated and if there are significant RTL issues we can iron them out.

[KhaledEmad7]

Yes, the UI is fine but there are still some missing changes needed to be done in the translation, I have made another PR for that hope it helps.

[KhaledEmad7]

The only change that can improve UX is making the front-end right aligned instead of left; however, the translation doesn't need any changes.

@KhaledEmad7 Have a look at #2302 and give it a try. :)
