Samsung Notes has a feature where you can edit your note on your tablet, using your phone for access to tools. This allows you to edit your notes full-screen on the tablet, and refer to your phone next to it for changing tools.
I'm sure you see where this is going. I edit in LR on my tablet, and find that if you could enter a mode on your phone which gives access to certain tools for the image being edited on the tablet, it helps to declutter the screen while giving a more efficient and tactile workflow. And for those who this feature might not work for; don't use it. Lol.
