Sumatra PDF is a lightweight portable PDF reader for Windows. While it is not replicating the complete feature set of heavyweight programs such as Adobe Reader, or even the third party alternatives Foxit Reader or Nitro PDF Reader, it is well suited for anyone who just wants to read pdf documents on Windows.
Sumatra PDF 2.3 has just been released introducing several interesting features to the program. It is a major release that is different from previous releases that just fixed a thing or two, or added support for a new format type.
Probably the biggest feature addition is the new advanced settings option which you find under Settings > Advanced Settings in the program or by editing the text file SumatraPDF-settings.txt directly (the link in the program opens the text document as well so that you do not need to locate it manually on your system).
A summary page with descriptions for each configuration item is available here on the author's website.
Here are a couple of things that you can modify:
- The font type, size and colors used by the program.
- The main window background color.
- The Zoom levels.
- Printer defaults.
- Whether toolbars such as the top toolbar or the favorites sidebar are shown in the program.
- Set a default display mode.
As you can see when you open the configuration file or the author's website containing the descriptions, it is a lot that you can customize here.
The inclusion of advanced configuration options is however no the only new feature introduced in Sumatra 2.3. The View menu offers a new Manga Mode that is available when you are reading Comic Book files (CBZ or CBR) in Sumatra. This enables right to left reading in the reader which can be useful if you are reading Japanese manga or manga published in languages that use a right to left system. Sumatra supports Deflate64 in Comic Book files now, as well as OpenXPS documents which it did not support previously.
The developer of the program has added two new keyboard shortcuts to it as well. You can now go up or down a page with the hotkeys Ctrl-Up and Ctrl-Down.
