updation needed in my page builder

I just need the following 3 updates in my page builder - my cms - [login to view URL] other cms [from where i need to copy] - [login to view URL] --------------------------------------------------------- 1. I want to add element in the end on clicking and drag up/down as in other, minimum loading time for the page [if you dont understand i'll make video for you] 2. save page userwise [currently preview button saved on server, we need to use same function but save userwise] 3. clone function for menu, slider as other cms and some css changes needed, load/backup wbuilder file from server itself for point 1 and 3 refer video - [login to view URL]
