In earlier Xoops versions could you choose on which pages in a module you want to place your blocks.
Now you can only place the blocks on all module pages. See the screen shot below to understand what i mean.
yes a very good feature, but modules may have many sub cats or in newbb case may have many categories and forums therefore it may affect the performance and I can recall the excuse of the last xoops core developer for removing this feature was the bad performances.
Also the customization will be limited to cats/forums and not for example each newbb topic or a single news.
maybe we can implement it by a different method. Trabis already introduced block anywhere smarty plugin and we need to just a user side/admin side ( i mean a theme/smarty ) online visual block editor like that work with some kind of jQuery drag and drop. i.e. you drop your favorite block in the page of your site you wish to see that block and it will insert the html code in the right place by getting some inputs from webmaster like $_GET variables in the URL. eg in newbb get the topic_id in a topic page.
with great block anywhere i already can insert my blocks really anywhere i want even in a single news or a specific topic (using topic_id) but an advance webmaster can do it. i taught we can make that easier for all webmasters.
