I use Master PDF Editor and think it is a good program. I have never paid for it, and have used it quite a bit, without noticing any missing features (I'm not saying there are none, just that I haven't noticed any). Another positive thing for me is that the developers are responsive to feedback (they're available through direct email support). They make frequent releases, and have a detailed change log: https://code-industry.net/what-is-new-in-master-pdf-editor-4/ My initial reservation for including it as a viewer is that it really is meant to be an editor, not a viewer. However, I just opened a multi-page PDF, and I can now see how someone might want to use it as a viewer (even though I would personally still prefer a more simple viewer): it seems smooth and responsive, and has continuous scrolling; and I'm not surprised by Uwe's finding that it has support for some feature that other PDF programs on Linux do not. One thing that annoys me is that the (major) version number of the software is part of the binary's name: masterpdfeditor4. So if we did include it, then when version 5 is released, we would need to add a new entry (or have a policy of only supporting the latest). In conclusion, I have no strong opinion. I just wanted to say that "I have heard of the program and find it to be a respectable program, compared to any other proprietary program I've used". So when making a decision I would summarize it as "should we add a PDF editor that probably not many LyX users are using as a PDF viewer?" I really don't have a good feeling for the cost of checking for another viewer so I don't know how to answer that question myself. I must admit though that I did (after checking on the list) add a relatively unknown PDF reader to configure: mupdf. Scott
