The new pages organization tool is more difficult and less intuitive, and its “insert page” option in particular is much less useful than it used to be, please fix it.
The most important problem is with the "insert page" function alone. When you select "file" for "insert page" it no longer lets you add more than one file at once. I frequently use Acrobat to merge several PDFs into one PDF and now I have to add each file one by one, this is incredibly time consuming, tedious, and wholly unnecessary.
Another problem I have with the new method is the size of the page organization tool—I can only organize pages in the left sidebar now, when before it let you see it in the main screen, which allowed for a larger view and to see the pages in grid order, instead of just in a tight row. This is frustrating as it makes it harder to visualize my document as a whole while I am trying to re-arrange it as a whole.
Lastly is a more minor issue. The first problem I encountered with it was the icon. In general, the icons for the new user interface are mostly too small and many are unclear. Further, they don't tell you what they do if you hover over them, you have to actually click the symbol to be given any description/text options. The icons in the toolbar aren't all bad, but it is very hard to find how to add, delete, or move pages. Not only is that icon in a confusing place all on its own, the little four grid square symbol does not intuitively represent that function. In fact, it is confusingly the same symbol used for switching between list or grid view on the open recents menu. So, when I fist saw it, I naturally thought it was just an option to view the PDF in a side-by-side grid view instead of just a single-row scroll. Please make an icon that actually makes sense.
