We are hoping to force people to login to our salesforce org through Okta using SAML but were curious if there were any repercussoins when we do this for mobile logins or any other tools that may be accessing our salesforce instance such as demand tools. 

I am working on opportunity products and came accross a youtube video where you were able to select multiple products and add them to one opportunity all from the same page. Currently, when we "select" a product for an opportunity we are directed to another page to fill out quantity, price, etc. is there a way to get that all on one page so we are not constantly going back and forth?
The layout in this video is the layout I am looking to replicate:https://www.youtube.com/watch?v=jQPTnfmHU2U
