I know, this is off topic here, but let me still comment on the unofficial version.
- Portable versions are essential for testing, as you can cleanly separate installations, settings and extension directories.
- For 4909, the maintenance of pre-installed plugins was important due to the instability of the online gallery access. This seems to be resolved now, at least up to now I did not encounter a single problem - Andrey, great work!
- for build 5151, a portable version can be generated. Still I did not test things like Mathcad EFI features, which required a special executable, provided by uni.
- Currently, we are focussing on a new release of the Maxima plugin (including the announced comfort functions for graphics). You can find the plugin in the SVN repository, it is not yet released to the gallery
- The active book help system is not accepted by ordinary users like my students, major problem is lack of search feature. There is coverage of many features now, but you need to browse the book a lot in order to get an idea where the required information could be. Also, I have no signals from Andrey, that any type of integration is going to happen soon (like the mentioned search, hot key for function's help pages, automatic interlinking to table of contents and browse history, up/down etc., not to mention link target editing support)
- Ctrl click can be avoided by making the pages read only, there were attempts to do that, but the pages are not correctly updated then (empty image regions)
- Initially, I had hoped for pages from other users, that is why the book is in SVN. In fact, there is not a single one.
- I had several feedbacks to the pdf manual from outside world, but none to the active book.
- Given these facts, I currently focus on updating the pdf manual. In principle it is possible to maintain a bilingual source in LaTeX as well but I did not test that.
- The pdf manual shall assume that you have Maxima installed. Thus, wherever there is a clean Maxima solution, I shall drop extensive discussion of internal workarounds. This mainly affects the CAS features and graphics.
- I might resume maintenance of the activebook later, because I still like the idea of an integrated help system.
