The unique and best part of Box app was the folder tree. When you hit the upper left button, there was breadcrumb type of folder path, which itself is usable knowing where you are at, and also you could jump to any of those folders with a single tap.
Also, when you want to access setting menu, now, you have to go all the way up the tree, change settings, and then go all back down the tree to where you were at. (Dropbox has setting menu in different tab).
I say, you should switch to Dropbox. It also has photoshop/illustrator file view, offline file shortcut, etc. Only major function not available in dropbox app is grid view of image files.
Great work copying Dropbox, but why cut the best part?
Some other advice...
1. How about adding Yoink (mac) type of function?
2. How about adding text editor?
