"Better than PyRoom in terms of appearance and features. "
"A friend of mine, who wrote his thesis (of about 1, 40,000 words), suggested this to me. I've been using the Windows version for over 2 years, and found little reasons to complain. I store around 6000 citations, along with annotations and links wherever possible to pdfs on my machine. The manual input method is actually a boon: it helps you identify and correct errors unlike automated fetches from Google Scholar and other sources when using software like Zotero, Mendeley, and EndNote. Also Zotero crashes often; Mendeley pretends to be free (asking you to upgrade after a point), and EndNote is... well, it sucks. JabRef is consistent, the easiest to understand, and the most reliable bibliography citation manager. Much thanks to the developers!"
"The best epub reader out there. It's much easier on the eye and distraction-free than Calibre or any other."
"Very high CPU usage. I prefer Dream Chess."
