Re: [xwiki-devs] [Idea] XClass Preferences

I would have liked that feature to stay as well. I see usecases for it, but I also remember we had problems with an application arriving on the wiki and imposing its panels, the Blog app. At some point, the Blog app was setting both panel sets, left and right, and we had an issue with that because we had setup the applications panel navigation for the whole wiki as a panel in the left panels, and the fact that the Blog app was overwriting it was a problem. * I can't control the color theme or the icon theme. I would like to use a I'm not sure I like that much the idea of changing the colors of the whole UI whenever the type of page changes in the wiki, although I see a usecase. I am wondering if a little color adjustment could not be handled through an SSX, pulled by the proper sheet at the proper moment. The examples you gave are still related to panels. I would be curious what other elements of the skin could be customizable by an application. Of course it does, but the other case makes sense as well (having the rights be controlled classically, by the place where the page is rather than by its type). What I don't like too much about these ideas is that we would basically be adding a mechanism that would allow a page type to influence the whole UI / wiki. Note that this is how currently the languages work (seeing a page in french also changes the languague of the whole UI to french), and we're not that convinced it's a good thing (I've heard it seen as a feature almost as many times as I've heard it seen as a bug). So, to me, it is good to have developement tools that would allow to customize these, and we need to be able to control these as a developer, but I think that an extra mechanism would add extra complexity (as Edi said) and still not be as generic enough as the development solutions we currently have (e.g. you wouldn't be able to remove the extra tabs conditionally, say, depending on the current user role). So I would be more for giving more control to the sheet (if we could improve some vms evaluation in the skin, for example), but keeping these customizable in the sheet rather than with an additional preference mechanism. I am still thinking, I see the pros and cons for this as well... Thanks, Anca
