File downloads are slower than before, and filenames are being altered with random codes.

Recently, I've encountered two major issues with file downloads. First, the download speed has significantly decreased—what used to take around 30 seconds for a 10-page EPUB book now takes 2 to 3 minutes. Second, the filenames of downloaded files are being altered, often replaced with random alphanumeric codes instead of their original names. This makes it difficult to identify and organize the correct files.

Hyperlink detection error

When reading links where a word has a hyperlink to the site i.pinimg.com it will be added to the top of the chaoter and the word erased rather than taken as a word.
Example in the link below the words "meeting room" will be removed.

Error when picking links from imgur.com

When picking chapters with words that have hyperlinks it will sometimes use null instead of the word + hyperlink. So far I have noticed this happens when picking https://imgur.com/ links which could be due to the lack of www or something else.
Example try creating one for chapter 1 of this novel.https://www.royalroad.com/fiction/84749/star-wars-rise-of-the-battlemage/chapter/1591480/chapter-1
Thanks for the help and the great tool!

Latest update removed option to parse multiple pages in parallel

Previously we could parse upto 8 chapters at a time parallelly, but single chapters are parsed one at a time and sequentially. Why was the option to parse parallelly removed in latest update

Improvement request

(https://wtr-lab.com/en/) this is a great website for novels and I want to make offline epub to read it on my own reader but web to epub doesn't seem to support it well I hope you check it out and improve it so that it can work on this website as well.

Can't figure out how to get epub to hold actual content, not related content in view

I want to copy TI Developer content to an epub. HTML is http:////www.ti.com/document-viewer/lit/html/SWCU185G#GUID-1CE51F25-50, but what's in epub is copyright, purchase information about chip, not "Technical Reference Manual". I'm sure it's a selector issue, but it's past my understanding. Any help would be great!
