Suggestions for PDF reader + site [add your WISHED for features here]

  1. For the SumatraPDF reader: When right-clicking a page in the ToC bar on the left, add a “Save to PDF” option

  2. For this forum: Add a “Suggestion for app” item, so users can easily add… suggestions.

Add an HTML file viewer

How to increase time of display of notes?

the best location for raising requests per documentation is

"Found a bug? Have feature request? Use issue tracker . "


Add an HTML file viewer, just like it does with a CHM file.

There is a problem - is it possible to increase the cache of paged pages in RAM? It is absolutely impossible to work with large documents, you have to wait for 8-10 seconds to load the page
Is such a possibility being realized in the future or is it already implemented but I do not know about this possibility now?


Would it be possible to make epub files scroll by the line instead of by the page. When I looked for a replacement for CoolReader the only reason I haven’t switched is because you can only scroll by page when its an epub.


The only thing that I’m missing every day are advanced search options. A quick way to get a grasp of all the occurrences of a particular word or phrase within a document would be a huge improvement and time saver. I keep a copy of STDU Viewer on all my computers just because it does this…
