On ELIS/Alfresco, was wondering if I should put a complete table into a landscape appendix or not, all side by side. Perhaps I should in next version of document.
Will check on the Alfresco aspect, I dont recall seeing that option to link to Alfresco via File picker alfresco plugin, mea culpa.
Regarding WebDAV this a tougher issue I guess. Its not really a repository and as you say, it technically could allow access to many different systems (including Blackboard). Each WebDAV interface on a repository has its own choice of how it exposes the local stuff. So technically it has potential to do anything or very little.
Perhaps I should flag it as a special case? rather than say it could do it versioning (which it could or it may not depending if the host webDAV server displays the multiple versions or just the one of the file). Something to think about.
On versions of software, the reason I hadn't added them was that it would "lock" the general document to one combination of all the versions and just require too much updating. My plan was to release, get feedback (like this) and then release an updated version after Moodle 2.2 is released -
Thats the general idea for each of my papers/e-books, to re-update the suite of documents after each major moodle release. But as someone suggested to me just yesterday, it may be good to have a number of people help maintain them rather than just me, which is an idea to play with too.
