Try Documentalist, my app that offers fast, offline access to 190+ programmer API docs.
This release comes a little sooner that I planned but I wanted to fix rendering issues that cropped in version 0.4 when I switched the default rendering engine from poppler to mupdf. I fixed all the issues reported on the forums and in the bug tracker.
But I didn’t stop there. I’ve also made some bugfixes and speedups so the application should feel more snappy and you should see “please wait” message less often plus I re-enabled predictive rendering of the next page (which got lost in version 0.4), for even better and faster reading experience.
Caching has been improved so SumatraPDF shouldn’t consume as much memory as it used to in long reading sessions.
I’ve added keyboard shortcuts for rotate clockwise and counter-clockwise (Ctrl-Shift-+ and Ctrl-Shift–, just like Acrobat Reader). This was suggested recently on the forums.
And finally I added an About menu.
