I've experimented a little with the Plugin functionnality, I tried to write a "Recommendation" plugin based on old issue analysis. The code is here : https://github.com/Liliputech/KohaReadSuggestion It kind of works, however I stumbled on a little problem. It seems not possible to run a plugin publicly (like public reports), one has to be connected to execute a plugin, right? Do you see any mean to overcome this limitation?

That's an awesome plugin! The answer is that there are no official hooks into the OPAC for plugins, but that hasn't stopped anyone yet ; ) If you take a look at the Ebsco EDS plugin, or my own Cover Flow plugin, you'll see we accomplish opac side functionality with additional Javascript. Mine is probably easier to grok: https://github.com/bywatersolutions/koha-plugin-coverflow Check out the install instructions and the module file. What I do is take the parameters set up in the plugin an autogenerate some javascript which is then placed in the OpacUserJS syspref by the plugin itself. If you need to access external scripts ( like mine does ) you'll need to add aliases to the apache config manually. Hope this helps!

= ReactJS = React is a JS library aimed to easier DOM manipulations. This topic is a recurrent one and developers involved in this discussion will be present at the hackfest. They should organise a discussion to reach a consensus once and for all. If accepted, it would be good to define guidelines and write complete examples.
= Koha plugin system = It seems that people are curious about our plugin system. It would be good to revive the discussion on new and more powerful plugin system. See the discussion on the koha-devel list at http://lists.koha-community.org/pipermail/koha-devel/2016-May/042673.html
= Transactions & exceptions = It would be good to see some developers organise a brainstorming session on the different topics that Tomas raised on his email to koha-devel a few weeks ago. http://lists.koha-community.org/pipermail/koha-devel/2016-Se ptember/043032.html
= Mana = Paul presented us Mana (https://lists.katipo.co.nz/pipermail/koha/2016-July/045739.html) at the beginning of July. Morgan finished her internship and will be there are the hackfest to show us what she developed. Testers and QAers would certainly be welcomed to test and review this feature.
= Hea = Hea is a website (http://hea.koha-community.org) collecting usage statistics from different Koha installations around the world. This feature is not enabled by default but is very useful for developers and other people loving statistics (so librarians isn't it?). If it is not done yet, you should enable this feature to join the 496 libraries already registered! One enhancement is developed and waiting for testers: 14608 - HEA : add possibility of sharing usage statistics in Administration page and Web installer
Hope to see you ready to fix, translate, test or QA patches (and drink beers when everything is done) this week!
