Did you google search, I think someone has already created this plugin/customization
Plugins only work well if a user does not have to edit code.
Have you tried using jquery to force the JavaScript function that loads more when the page is scrolled past the load more button?
Hi, @modemlooper I researched a lot and there’s no one who did this, maybe you heard of myself since I wrote a kind-of-tutorial here at the forums explaining how to achieve this, but I would like to make a plugin with it 
I have all the work done, you can see a working demo here (scroll down to see it in action) http://www.horizontea.com/ the thing is I do not want the “Load More” button to appear since the user won’t need it and the appended items will have problems with the way that the new instances of the button are created…
I just want to know how some plugins code manages to “rewrite” some theme parts from backend, not frontend, if such a thing is even possible. For example I want to replace as explained in https://buddypress.org/community/groups/creating-extending/forum/topic/auto-load-more-activity-stream-items-when-scroll-reaches-the-bottom-of-the-page/ (I have poolished and improved the code now loads only when needed and included throttling functionality).
If it cannot be done it will keep being just a tutorial and never a plugin, sadly 
For example here in this WPMUorg tutorial the author explains how to replace some piece of code, but it is passed as a variable in the execution time, after it’s assigned with a value http://wpmu.org/how-to-create-your-very-first-wordpress-plugin/
Will it work if I want to modify the php templating code BEFORE it gets parsed by the PHP engine? I think not…
Hi, maybe someone just can tell me how to programatically set a custom template instead of a given one? I need to change the activity loop template inside the user’s current theme (as a child theme would do) but my “product” would be a plugin, not a theme.
I can’t use filters since I don’t want to modify the dynamic content but the template php logic.
Please I hope someone could point me in the right direction… or give me some advice on what is the best practice for doing this if I’m thinking it wrong. Thanks a lot.
