In the new version I just couldn't upload my file, so I address my issue to the former version:
When Hebrew or Arabic text is mixed with English words in the text, the sentence's order is garbled because the parser does not understand the left-to-right alignment.
Messages with only one language come out alright, except that emoticons and punctuations at the end of the message are written on the left instead of on the right, again because of the same issue.
Thank you for your great software!

I address again my issue to the former version, as I didn't manage to load a chat to the new interface.
I would very much like an option to pre-define the chat's parameters in the HTML, so a single chat could be load automatically, without user intervention.
This is for displaying a fixed single chat on a website.
So that one could define in the HTML the chat's filename and the main speaker.
Thanks again for your great project!

The website looks really nice, but when I upload the text file and should choose my name, it shows only the first sender and it's bound with the time and date. For example, the beginning of my .txt export file looks like this:
23.10.20 22:49 - MyName: ‎IMG-20201023-WA0017.jpg (soubor byl přiložen)
and after I upload it, the prompt shows just one option:
.

As a result, the whole export is like just one message and is on a single line.

Hi. Your chat viewer is the best I found.
In the Whatsapp Android app you can press Enter for a line-break, without sending the message.
When I export my chat from an Android phone and upload it to your script - every time there are line breaks in a message, only the first line of this message is displayed, and everything written in this message after the line break is ignored.
Thanks for your great script!
