SmartApps - Configuring

I am relatively new here, with the SmartThings system, but am very happy so far. I did have some issues with conflicting SmartApps on the same device (front porch light). I use Android (Galaxy Note3 and Galaxy Tab) to manage the system, and found the setup confusing. I’m hoping that the developers can tighten up some of the terminology used, and create more of a “Theme” model, where lighting themes can easily be added to devices. Currently, in the Android App, the reference to SmartApps, and the following instructions to add another Light/Switch (really a lighting theme) was very confusing. I submitted screenshots to Support, but can’t upload them here as I’m a new user.

I’m installing a drop cam tonight, and an ecovent next week - looking forward to seeing how those work.
