I implemented two of your hints (see history).

In order to calculate the display time of a progress bar, I stopped intermediate times in the program flow. To my surprise, the HTML rendering of the text browser widget consumes 2/3 of the total runtime! I may implement in a future release a workaround like stepwise asynchronous loading with a timer or so, but I need to do some research on that.

Thank you for the mention, I appreciate it!
Just did a quick test and confirmed that I had two identical books (Ratio 0):



Then I found both are sourced from Gutenberg (one is a StandardEbooks edition).
Dark theme on-screen output is fine now, and it's great to have a one-click TextDiff tool within Calibre, thank you again.

The ratio is described in https://docs.python.org/3/library/difflib.html: »Note that this is 1.0 if the sequences are identical, and 0.0 if they have nothing in common.« Hmmm...

yes I found it interesting to be zero, because when i did previous comparisons with very similar texts (translation variations), ratio would be like 0.95 or so

then I thought it was the other way -- the lower, the closer to identical
