I just added a link to an all-in-one installer for the required Python stuff for Windows on my description page. It will make it easier for Windows users to get rolling:

If you haven't tried the latest version, I've recently added direct-download support of several LDS class manuals and documents within the Thummim application (no separate desktop app needed.) These docs are all small enough they download in just a couple of minutes from your Nokia.

I actually ran the ldsripper app on my Nokia, but I found it so slow to be pretty useless trying to download books as large as the Old Testament. I think I will probably never implement that directly on the handheld.

I've also added the ability to copy text from within Thummim for use elsewhere and cleaned up and enhanced the notes section. I also added a click timer to keep you from accidentally causing phantom clicks (double clicks) when using your fingers. I was having constant problems of skipping pages when using my thumb to change pages.

The last feature I still want to add is full text search.

On the topic of speed with the Plucker docs, no doubt that's the problem. That's why I designed Thummim to load only a few K of text at a time, just enough to fill the screen. You don't notice any load delay when you click next or previous page, but that's when it actually loads the text. That's the reason my files are stored in plain text as well, instead of compressed.
