After a few months of active using it I noticed that sometimes it completely ignores big part of a web page - the worst part - somewhere in the middle.
So - it has a good beginning and good ending, which makes very hard to notice that there might be something wrong.
That's not good - I would prefer if it wouldn't work at all in those "problematic" sites as then I would know right away I have some issue and I need to use some different solution.
Because of that I had to retake all my web sites that I'm archiving as epub.
