I often use offline time (e.g. when on the car/train/plane) to read articles pulled from the web. To store the content, I currently use Firefox's Save Page As. (Note that's not recursively downloading entire websites, but just individual pages plus their styles, images etc.)
I have looked into automating this, but neither wget nor HTTrack give me what I need (it's either too much or too little - or even both).
Any recommendations would be most welcome!
